Happy days
Just change Oil, New filter drove car for about a Week, I had the car running now for over a year after replacing the ZF transmission. Car has 198000 miles,
Order new coolant hose both upper and Lower. When to flush and replace old hose's. Open the coolant cap. Found Oil mix in, Ahhh I so **** now!!!

Now I need to pull the head off, send to a shop have it check, Replace the Head gasket, along with other Items.

Looking for any pointers and special tools to remove head and Keep the timing chain in place as I service the head.

Any Help at all
Thanks
Happy Holidays,
Keep driven fast

 

Whoah, might not be that bad.


Is it engine oil or transmission oil?


An internal leak in a transmission cooler can do just that.

Tranny oil getting into the coolant, (and vice versa), is a well-known syndrome on these cars. It is very unusual for engine oil to get into the coolant, although there are some rare circumstances. The transmission cooler was in the large coolant pipe at the bottom of the radiator, and this corrodes letting the two fluids mix. Neglect of keeping anti-freeze up to strength and replaced regularly is the main cause.

 

Agree with that, trans oil the most likely culprtit, or steer oil, BECAUSE,

He is mentioning a ZF transmission, not fitted to the Series cars that I remember.

His "profile" states he has a 1955 XJ-S, so a TYPO I reckon for a 1995, and would assume a 6cylinder 4ltr AJ16.

I did ask the car details before, but no reply as of yet.

Maybe a repost in the XJ-S or the X300 section would be more appropriate.

 

Put engine in TDC. Cil #6 & 1 in compression stroke (camshaft knobs facing outwards) and look on the crankshaft pulley.

This should fit on camshaft (more important for installing back):


Remove safety wire and unscrew bolts of the camshaft gear. Slide it up and secure it with a ziptie.

There are 6 bolts in the front of the engine that need to be unscrewed first + 2 oil feed pipes to the cam on the back of the engine.

Other than that nothing special. The tool cost me €10 and I bought 2 just to be sure. The notches might not line up perfectly, mine was slightly off but I ran the engine anyway and it was fine. Did 100mph easily.

Always test before you do radical things, to be sure of everything. Sometimes, not everything is what it seems. A leaky manifold might leak coolant into the cilinders for example.

 

Yes I do have a 1995 XJS AJ16 motor, With a ZF 4 speed transmission. did check transmission and power steering fluid, No sign of water: Oil dipstick, Transmission dip stick or power steering.

Any special tools or trick's on pulling head off an timing chain in place???


To Be honest driving the cat is fun and very fast, Now I need to bring inside and once more do repair work. Most of my ASE friends that how the Jaguar tail wag, so I need to trouble shoot the issue's an repair. Its winter time now, spending the working, and not playing

 

Thanks for clearing that up for us all.

This "Series" section does NOT use that engine.

My suggestion, again, is to ask in the X300 (that engine is standard), and/or the XJ-S section, where that engine is used, but less common.

It will NOT be anything special, but I have not done one yet.
