...the other night i did a compression test on the s type and i got steady readings on all cylinders except the last cylinder on both banks. Is there a special procedure on how to do it on this particularcar or should i just accept that i have internal damage or possibly a bad head gasket for those cylinders.
any help is greatly appreciated.

 

the lowest was 145 and 165 being the highest. I did a compression test because ive had a misfire issue for quite some time and when a friend of mine hooked up his scanner, it said it had a random misfire(all cylinders) I turned the car on just the other day and it ran like crap. i pulled the plugs and are fouled as they had oil on the side. coils might need replacing but valve cover gaskets for sure. I ask because i got 0 reading on the last cylinder on both sides. ill try a wet test tommorow see how that goes

 

I am having a misfire issue at present. About every 15-20 seconds when the car is stopped. I am suspecting a compression issue as well.

How did your situation turn out?

2000 Jag S Type 4.0

90k miles.

Past problems:

Compass in rear view mirror went out (fixed under warranty)
Drivers side window would not roll up (fixed under warranty)
2x thermostat went out (under warranty)

Not bad for 7 years and 90k miles!

Now I'm out of warranty

 

Thats too bad.. I will keep you posted. Initially, I was thinking that it could be the fuel filter, or fuel pump, but maybe not.

I can't wait to have my car back!
