I hope I don't ruffle feathers but I need to ask. I don't mean to post the provoking question that will start a round about...

Folks here are a LOT more knowledgeable, tolerant and kind (to tell the truth) than on the Rennlist forum, so I'll ask here to see what folks think. (Hey, it's just been my experience).

Questions to do with KEROSENE...

I have a 1986 Porsche 928 that sat about 4 years. V8, 32v, 5speed manual... I have driven her some but very little and changed the oil once with a cheap-ish 20w 50. I have lifters that tick like crazy (especially at start up), 4 to 5 I think. She runs BeaUTifullly for the most, I must say. Needs lots Of love... I've spoken to the previous owner who doesn't report the ticking and raves about how fun she was.

Anyways, she holds about 1O quarts of oil. I have a feeling, that from the long sit, that a gooooood engine oil flush would be a good idea. Goo and crud...

Should I use some product flush or good old kerosene/diesel flush? Add some quart(s) to the oil,,, idle for 10-20min and drain? I'm skerd! And should I be?

Looking for advise here and anything, even if it's admonishing, is very welcome.

If so, what ratio? How much solvent would I add?

 

Cheap option: 2 Liters of ATF fluid, drive 100km or 62.1371 Freedom Units then flush.

Slightly more expensive option: LiquiMoly Pro Line engine flush, follow as per instructions.

Afterward followup with good oil and something like CeraTec or Archoil friction modifier. Personally I use Delo 15w40 advanced deisel/semi truck oil, longer life and proper soot control.

 

ATF
And drive, you say?

The folks on the Rennlist forum make me scared of my own shadow,,, hence the question - risks?

Shoot, I have a half gallon of fairly high rated ATF right here.

 

Grant said use ATF, and like god issueing 10 commandments it was so.

ATF is very light and has cleaning agents. Its on the same thickness as 0w20 (i think) so no harm. I do it all the time in high performance diesels, and my jags.

 

I hear ya!!!
And I likes me some GF from down-under...

Don't take it any kind of way,,, but I am still gunna listen to what others might say. I've been thinking of the ATF, myself.

I think I heard Grant tell a story about FILLING an engine with diesel or kerosene once, as well. Solving a different problem tho

 

I also have a 928.

At my AirBnB in Uganda, I hosted a delegation of Germans from LiquiMoly. They worked over both my LandCruiser diesel and my 1992 S600 Mercedes that sat for 5 years in a refugee camp in Juba, South Sudan

They pulled valve covers and oil pans to record baselines. Then ran both their oil products and their injector cleaner thru both cars.

i was blown away. I usethem on my 928, as it sits for 10 months in storage here in the states.

The most incredible results I had on my boat engine. Nissan SD33 Turbo, 1975. The difference in how it performed in terms of smoothness and power was unreal.

I am a convert.

 

The Moly flush product? But I understood that it's basically kerosene,,, with some special sauces...?

 

I posed the same question. The Materials sheet the showed me said otherwise..

I have tried kerosene on my LandCruiser, and did nowhere the cleaning their flush did

 

Damn dude... I want to know more about your story, lol. Just say'n...

 

I've used ATF in too many engines, for all sorts of ailments.

Drive it if you MUST, NO harm, unless you drive it stupid, bear in mind the engine is ILL, the ticking states that.

On my latest fleet beast, a 2010 X Type 2.1V6 Front Wheel Dive, the oil was GUNK, so I ran 1ltr (6ltr capacity), and let it run in the driveway. I did other things, beer, sparks on the V12, beer, washed the S Type, beer. 3 hours later, shut it down and drained it, OH dear, that STANK.

Repeated 3 times same day, no more sparks etc, just the beer.

That was in October 2018, and the oil stays CLEAN from initial fill to change.

Productive day.

Kerosene,

Dad used Kero as a pre drain flush on the MK4 and MK5 Jaguars, nothing else available way back then, but they were/are very different engine internal specs to what you have, as well as the latest stuff. I would NOT use it in a a modern Hydraulic VVT, lifter engine under any circumstances. MY OPINION onl, NOT based on Science.

 

I get that a lot...

Ive been living in Rwanda, Kenya, S.A. and Uganda as my home bases since I went to work with the UN during the genocide in Rwanda in 94. I was a non tenured professor of engineering in Chicago who got bored.

Since then Ive Lived and worked for extended periods of time in Vietnam, Cambodia, Laos, Afghanistan, Jordan, and Iraq. Mosul was a cool place until Blackwater.

Im also a lifelong sailor. Did a 2 year circumnavigation in a Warrior 38 during a break in a 20 year university stint. Ive got sailboats on Lake Victoria in East Africa, the Med, and the Olympic Peninsula In Washington. My official stateside home is my boat, so, by Wa state law Im considered homeless..

Im also a gearhead. Being based a while back in Baltimore I started storing my stateside cars and bikes there. I am trying to get 4 cars and 3 bikes moved to the Seattle area where my boat is.

And with a bit of luck Im going to be able to ship my S600 from Uganda to Wa state as well. I spent 3 years restoring it, carrying all the pieces in my luggage from Europe and the States. A UN relief worker brought it over to East Africa from Japan, and commuted from Uganda to Sudan with it over some of the worst roads imaginable. He was killed by Jajaweed rebels in Sudan. It sat there being used for target practice for several years. When I was shown the car, it was full of bullet holes and pretty trashed.. The sight of Benz’s flagship V12 in a refugee camp was too much, so I flatbedded it home to Uganda.

My 928 I found on an island outside of Vancouver. Brought it to Seattle, gave it to a shop for 3 months. Then drove it to Central America and then back to Baltimore. Hell of a road trip for 7 weeks.

Since semi retirement, springtimes are spent sailing the Med On my charter Morgan 44.. During summer and fall I live on the water in British Columbia, cruising the Gulf Islands on my Islander Freeport. Winters I spend in Africa, where Im either on my Alpa 9.5m sailboat or sailing dhows off the Kenya coast.

And I agree, Rennlister’s can be rather obnoxious at times.

I also cant insert pics worth shiite...


It has come a long way

My Egyptian Hydadid Ibis guarding the S600

 

I once found an outboard boat motor half buried in the mud on the family farm, it had to of been there since the early 00's. 1 good soak with liquimoly flushes and treatment with friction modifier ressurected that heap of crap. Took it fishing the same week very smooth for a formerly rusted boat motor. Somethingsomething german engineering it just works.

 

can’t help with the original question, but I see other XJS owners here are also fans of the 928. I only have Jaguars in my garage, but man would I love to bring one 928s home, with the original rear end pre 1986. I have lots of cars I like but would probably never bring home, but I don’t think I could say no to a 928 under the right circumstances.

 

l used to (for my sins) have a HEMI Jeep, notorious for ticking lifters, Seafoam (and a catch can in the long term for the jeep i believe) is the go to for most and it worked for me.

l have a 1950s D7 dozer, it takes 30w in just about everything, in very cold weather the manual states to cut the engine oil with kerosene.

lve heard tale that Seafoam , etc etc is just 'tarted up'' kerosene, however, im no chemist (although given the consumption it would have probably been very cost effective in the 80s)

Moral of the story, im sure both would work, but considering the cost of potential damage i would at least for the first attempt spring for a couple of cans of seafoam or one of its counterparts, as in something made for the job at a ratio that isnt well intended guess work.

Cheers

 

Wow Scott... what an adventure and a life.
Makes my life of work and kids feel like a waste of time, just getting the kids to the train on time each day feels like a war zone in our house!
Seriously well done.

And this is coming from a global warming sceptic, but I have to take my hat off to you!

 

Dukejag,

i find very few people’s lives wasted. Raising kids to contribute something to help others is the greatest thing any of us can do.

I’ve raised two daughters (actually my ayah and the village I kept in my compound did), and I think they turned out pretty well. Although they both totally disdain all forms of petroleum based vehicles.

I sometimes wonder what they are going to do with the collection Im leaving them....

 

Good Morning... As usual, great advice with great visuals (maybe one day I'll get to see the Grant with wrench, motor and BEER) to sum it up...

ATF it is and will be then! I can do that this weekend! Sounds good! Maybe a mix of the Moly and ATF...? Couldn't hurt, right??? Then, folks say a good oil 20/50 oil with zinc in mind...

She's worth it... Can't wait to have her right!

 

My 928, headed to Limerock Tomarrow.

Since we're on Renlist now... I'll chime in.,, Yes the lot over there can be a prickly bunch, myself included. As for your ticky lifters, I had success with "Marvel Mystery oil". You may have to up the dose since the 928 uses about 8 quarts of oil. You also want to run a thinner oil fill to allow the oil and it's cleansers to get thin enough to penetrate into all the small pores of the lifter and free stuff up.

Here's what I would do....

1. Drain out 4 quarts, add 2 quarts of 0 weight oil.

2. Refill the rest with Marvel Mustery Oil

3. Drive it for days, gingerly but let it get hot.
(oil may never get hot enough to thin out and clean varnish, This era 928 has an oil cooler. If still noisy live with it or Proceed to Nuclear option 4)

4. While idling at about 1000 RPM block off a portion of the radiator so it gets hot, just below the brink of over heating. You'll know it's hot becasue your electic 2nd'ary cooling can should come on.
The thin oil, the heat and increased high idle oil pressure will break down the varnish. You really need to be a good mechanic to pull this off safely but it will work. If not then you'll have to live with a noisy lifer or dig in and replace them. If it starts to boil over remove what ever you used to block off the radiator (card board) and it will quickly cool down as long as your clutch fan it good. AGAIN, I STRESS YOU REALLY NEED TO UNDERSTAND ENGINES to safely live on this edge.

5. Wait for noise to go away. Might take awhile. When it does let it cool down. Change oil filter, refill with half Mobil1 15w-40 and half 15W-40 Rotella. Done!

I would also replace the oil filter with a Porsche one after it's all better and you go to your final oil fill.. Noisy lifters is supposed to be part of 928 ownsership but mine doest make any lifter noise even after sitting for weeks.

Jag's especially the V12 dont suffer from noisy lifters becasue they get hot. 928's are over engeneer'd and dont get hot unless pushed hard. Mine will be pushed to the limits on Saturday at Limerock and will get hot but most 928's do that.

 

Not the best pic, but its what I have on my phone

Perhaps we should rename this thread. Something about 928s...
