Any cures for an oil leak at the camshaft timing oil control solenoid on the front of each valve cover?

Looks to be no longer serviced and no mention of separate o ring/gasket, etc.?

 

AJ133 gasoline V8?

You said "at". Could it be "through"? As-in a cracked device body?

The position sensors aren't terribly expensive. I haven't chased the actuators.. yet.. but the greater concern is if the leak is a product of deterioration of the controlled VVT device itself.

Those are rather dear...and require the whole complex dance of timing chain, guides, tensioners, and sprockets to be at least "gotten to", if not also replaced.

How long since your timing chains were serviced?

 

A simple replacement of the oil seals stopped my leaks? The rubber hardens and then leaks. Have replaced them twice in last 6 years!

Errrmmm... Dubai does have some rather challenging weather?

Originals on mine aren't yet leaking. Mobile One oil, most-recent change.

Bought the two spare sensors in case I break one doing the new chains. Didn't even twig to them NOT coming with new seals.

Thanks to the both of you, I shall now order those as well.

 

Thanks for the part number.

How difficult is the job, how do you get them out?

 

Depends on how brittle they've become. Might pull right out.

Covers off as part of a chain replacement, just bump them out from the "inside".

From photos on AJ133's V8's on Rovers, it is wise to not risk broken-off plastic bits getting left inside the motor. The shards can end-up partially blocking the intake screen of the oil pump's pick-up tube. That can lead to far worse things than a minor oil seep.

Could be wise to grab - or fab - a hook to reach through the bore and pull them out so as to NOT pry on the external lip and risk that unwanted breakage?

 

So if all goes well, it is not too bad of a job at all?

I found this, it went well for him :-)

 

Piece of cake... compared to replacing the rear plastic cooling system crossover tube.

Person should eat a live frog before starting THAT one.

Not much less as has the probability of making the rest of the day seem an improvement.

 

Should be able to pry them out without removing anything?

"Should be" died back in '47. I were at his funeral.

Nothing forces you to follow the advice of those more cautious.

But when a person with enough "earned the hard way" scar-tissue on his **** to upholster an entire 747 airliner sez to minimize a risk?

Do as you see fit.

 

Your car but this has been done dozens of times and is a good time saver.
Try it and see? I don't think you have actually done this?

You know how some people have "luck". Or not?

I were he who seemed "blessed" - early-on - with the ability to find a way to prove Lybarger's Corollary to Sod's Law each time out.

"All else being equal? YOU LOSE!"

So I taught myself "caution".

Even keep a few damaged tools and parts - 1950 onward - within eyeshot... to remind meself.

It was faster and cheaper to do some things the longer, slower, way.

Besides.. with a menagerie of 'hook' tools and extractors accumulated since the Devil's elder Brother gave up cornbread for Lent? Have to justify their storage space ever' now and then. Even if only to refresh my mem'ry where I most-recently stashed 'em

You may be more fortunate?

I surely HOPE so!

 

The video shows how truly easy this job is. To suggest that a person who is incapable of following the steps shown in the video, should start pulling the valve cover, knock the seal out from the inside, replace the valve cover with new gasket and 4 spark plug boss seals seems to me to be asking for trouble. My experience, with the half dozen I have replaced, has been that sufficient oil was leaking to keep the rubber pliable enough to remove as shown in the video,

 

That was not what was suggested.

Not unless one was already having those parts off for a chain and tensioner repair.

What WAS suggested was use of a common "hook type" tool inserted through the bore of the bushing so as to PULL it out with pressure on the inside edge, not by grasping the outside lip.

That to reduce the possibility - however slender - of a badly deteriorated bushing breaking and dropping bits of itself down inside the motor.

If you don't want to, you don't do so. Just a difference in technique, not politics nor warfare.

No more complicated than that. Not even any significant difference in time required to do it either way.

Besides.. I don't actually CARE how some other person goes about a task, and doubt very much they give the least dam' as to how I do my tasking EITHER?

Not as if it were as critical as a hemorrhoid transplant - where the new tissue might reject the host - is it?

 

Bingo Six!!
We have a winner!

Good.

Now .......it's too early in the Eastern Time Zone... but
as Prior Planning Prevents **** Poor Performance, may as well check in advance?

No Fear. Cork is still sound.

Even if it looks as if this bottle of Old Pulteney is going to last another ten years.

The other three stashed are "trading material" for food, fuel, ammunition, antibiotics, blood plasma, heavy weapons, Jaguar spare parts, Rover spare parts.. and other essential survival stuff .. just in case the whole dam' world goes pear-shaped.

I did say "cautious"?

Wuddna' want to put yer trust in something less valuable, such as Gold or Diamonds, wudja?

Wellll.. maybe several sets of Genuine OEM Bilstein air struts?
Lighter than Gold for similar value, yah?

 

Still pretending that you know how to do this?
I suggest when you find yourself riding a dead horse....dismount!

Ah the internet experts we see!

Are by chance the same guy on Practical Machinist?

I don't see the problem that has you all wound up, emotionally? It's only a freakin' PART!!!

"Pretend to know how"... to pull a seal or bushing out of a hole? If you want to pick a contest of skill, how about picking something hard?


It isn't about "if". It's about "is there more than one way to do it".

- The "majority" method is to grasp or lever the exposed outer lip to remove. Glad it works.

- "A" minority method is to extract with a hook tool. That works, too. Don't believe it? Go try it.

- IF/AS/WHEN convenient, cover already off and asided, push out from the back. Easy enough?

"So far" no one has posted having to saw it apart, heat it with a torch, or bash one to flinders with a hammer, so no need to go there.. we've already BEEN there ...on less cooperative goods... have we not?

In general, the more ways we have to approach a(ny) challenge, the more options we have to choose from when dealing with the NEXT challenge.

That cross-fertilization and extrapolation is a core part of how broadening experiences expand and extend our capabilities, improve our speed safely, and better assure success.

Seems as if "shared knowledge" is a feature, then... not a bug?

We always have to make our own choices AMONG available options, do we not?

Do so. Whatever works best for YOU. Others will do the same. For THEM. May or may not be the same choice? Life works that way some days. Just deal with that.

Be happy we even HAVE "options".
