I have considered buying a 5.0 litre engine and seeing if I can match the internal components, or have them made from higher grade materials.

Did you measure the bores to check for any distortion due to overheating? Did the cylinder heads require any other work besides resurfacing?

 

you can order custom pistons through JE Pistons. With this engine rebuild he could have ordered a different piston instead of using that shim but it would have added like $1500 on that bill.

I always wondered why I had never seen a pro charger or turbo install on an F pace..... now that I have seen the block I understand why!

 

We don't know how much the head was warped. Yes, lower compression pistons can be made, or with cut outs for valve clearances machined into the piston crowns. I believe this is a normally aspirated AJ133.

Unless you can remap the ECM and TCM to accommodate the modifications, the vehicle will not perform correctly.

I don't know where you are, but here in California, vehicles with extensive modifications will not pass the visual and OBD scan emissions inspections.

 

I live in the Dallas area. Here we have emission check also but they use a OBDII scan tool to look for codes so pretty much no check engine or ABS light the vehicle will pass. The computer can be retuned, Hennessey is currently offering a 616HP F-Type that comes with a 3 year 36,000 mile warranty on it! If you were going to build a very high HP race version of one of these cars I would think you would need to work with BigStuff to get a ECM that would allow you to truly unlock the power potential of a big boosted application. After seeing pictures of this block I highly doubt it would be able to handle a big boost set up making close to or over 800 HP!

I am new to the Jag world and I really wish it had the aftermarket support like Ford or Chevy but that cant happen because the demand is not there,

 

I took .010 off the block surface and .010 off the heads. the shim is .020. and of course a lsx would be better

 

I may be looking at things crosseyed, but isn't the shim going to block off some coolant flow from the block into the head?

 

No more than the head gasket itself.

 

This might be a stupid question for you... Could you possibly do a concrete low fill on the factory Jag block to reduce the possibility of warping the block? I have done a low fill on a .100" over (505ci) BBC street motor in the past with no issues but I wouldn't recommend that to anyone. I know concreting a block is mostly used in race applications but a low fill still stiffens the block significantly and COULD possibly provide adequate cooling. I know you would not recommend this to your customer because of the risk involved, but hey were are just talking in a forum!

 

no questions are stupid, that's why there's forums, to help one another. as for the question, i'd say absolutely not, the depth of the chamber surrounding piston bore is less that 3 inches, there is no coolant below the piston when its at the bottom of the stroke. I believe that's why its almost catastrophic when it suffers a simple water pump failure.

 

California and states that use California Emissions Standards also do a visual inspection. Aftermarket inlet setups and exhausts are a failure unless the parts carry a CARB certification number for that specific vehicle. Texas obviously uses a different approach.

A few years ago, Jaguar produced an experimental 1.6 litre petrol unit for the C-X75 that was both turbocharged and supercharged. Coupled with the electric motors at each wheel, the C-X75 was able to deliver 890 horsepower and 1,180 lb-ft of torque. Unfortunately, the C-X75 was cancelled due to changing market conditions.

Jaguar is a premium brand, not a mass market, high volume producer. Most of the owners are more interested in comfort and style than horsepower. Besides, I believe very shortly there will be no more eight cylinder engines produced by most major manufacturers as they focus resources on developing hybrids and fully electric vehicles.

 

When do you anticipate having the engine running?

 

Did you meet with success on the engine repair?

 

Seems I was looking at the shims cross-eyed.

Meanwhile, the silence is deafening....

 

motor is back together with no issues during assembly. My part is done now its up to the techs to install.
Not sure when that will be, but will definitely post the results. good or bad.

 

Wow!!! Thx for updating and good luck!!!

 

What happened when the Technicians reinstalled the engine? Did the engine run properly?

 

Was the engine reinstalled and did it run?

 

I keep checking back as well.

 

sorry for the long wait, techs finished installing the 5.0 jag motor two weeks ago. start up was spot on and after many
test rides, short, long, hard and easy, everything seems perfect. at this point i'd say it can be done. I was lucky to have a
good unit to start with, if you consider overheated so bad it warped the block and heads quite severely. but the motor
showed no signs of bearing wear or scorching. hope this helps anyone that is in a jam and just can't get out from under it,or
scrap it. a shout out to innovative machine and supply ( Innovative Machine & Supply - Home ) they make head gasket shims that made this job
even possible. they can custom make a shim off your head gasket or they have many applications on file. thanks all

Is your engine still running fine? What did it end up costing you? My XF has a blown head gasket. I already tried installing a used engine and that engine also blew a head gasket (within 200 miles). My mechanic thinks the gasket on the used engine was warped. The cost of another used engine is about $5500 and the labor was $3500 to install (labor and new parts). I got a refund on the engine but (obviously) not on the labor. I don't want to go that route again and risk losing another ton of money on labor. I'm in California, btw. I figure if the cost isn't too bad, it might be worth a shot. It seems my options are limited at this point.

It's a 2011 XF Portfolio 5L V8 w/54K miles on it. Excellent condition so it kills me to take the loss. With the blown head gasket car runs rough and will let coolant in the engine after driving only a few miles. As soon as engine gets hot it misfires and goes into restricted performance mode.
