The 'E' Type Forum

Hello,

I'm from Germany and I bought an E-Type Series 2 OTS in April. The Car had an engine in that was rebuilt by XRN Engineering in the UK and had jast 1000 mls on the engine.

The engine has big problems with the cylinder head.

Does anyone have experience with Engines from XRN Engineering??

They rebuilt my S2 head 10,000 miles ago and I've been very pleased with their work. They do lots of triumph stag heads and blocks and generally I believe have a good reputation. Suggest you give them a call to discuss your particular problem.

I have no connection with them other than being satisfied with the work they have done for me.

What does the head do that seems to be the problem, can you say?

Have you consulted with a Jaguar psychiatrist? They are usually good with head issues. But the head must really want to change!

My solution, take two valves pills and call me in the morning!

LOL!

Jokes aside, can you tell me what is wrong with the engine?

I'm pretty new in the E-Type business. I try to find out know if my workshop tells me wrong things.

The Problem with the engine is as follows:

During a general inspection, the Workshop found out the the head was leaking a bit of oil all around.

I have to say the engine ran perfect it had now smoke, there was just a lot of water missing.

In the end the head was removed and it was found out the the screws and aslo the studs (long studs) were pretty lose. The engine had arround 2000 mls on. Additionally there was oil standing in the inlets. I was told that this oil comes from below and that it could mean the piston rings are somehow wrong or even more.

Up to now the head was straightened again (I was told that this is necessary for sure). The valves where controlled and some edges were reworked and rounded.

In the next step they want to remove one piston and measure the piston and the block.

I really hope that this will deliver a good result, because otherwise it will get really expensive, and that for an engine that has only 2000 mls.

So the head warped. This is an overheating issue.
Did you notice that the engine ran hot?

One other issue to check before you pull a piston out, you mention that the studs were loose.

The bottom of the studs are seated at the bottom of the engine. Thru time rust can settle in the grooves of the treads that hold the studs. Do you know if the studs are new?

Can you make sure that the tork required on every stud was properly applied.

With only one defective tread at the bottom of the engine, you will not be able to tork properly the bolts that hold down the head. This will create a leak. Oil and water will seep out from the head gasket, just like your car.

You mention the fact that one or more studs was loose.
Without taking the engine out, you can retread the bottom of the block in order to have properly seated studs.

I did that on my engine. Stud replacement is not expensive (compared to taking the engine out and doing a piston ring job).

What will need some skill is placing a new tread at the bottom of the engine, if that is your problem.

However a good engine builder, one that knows how to replace sleeves and bore your cylinders will do that in a few hours.

I had 8 of the 14 studs with that issue. With the engine out it cost me $100 per stud. Once I rebuild the full engine and torked the head on, two more tread broke... I had to do them and at the same time all the others not yet done with the engine fully rebuild. We did not disassemble it all.

Those ones requires longer drill bits and a bit more skill but ended up costing me $150 each.

If you only have a few loose studs, try to ask your mechanic if this would help your oil/water mixing issue.

I can clearly see a mechanic rebuilding this engine not wanting to reopen it after he did the full reassembly and over torking a stud or two...

Where in Germany do you live?

I'm from munich.

I hope tomorrow I will know more about the engine.
