hey everyone i'm new to the forum and i've searched and found some useful information but im still stuck with one thing

so my s type is misfiring its at 204 thou kms and god knows when the plugs were changed last

i was able to remove the cover on the passenger side easily enough and changed up the spark plugs on that side...my only concern with that side was the there was a little bit of oil around the old spark plugs...not sure if this is a big concern or not

but the real problem is changing the drivers side....i cant seem to get 2 of the bottom bolts on the cover at all...i really need some help with this guys...i tried to find any pictures/videos even but can't seem to find it.

also, the coils seemed to be clean and theres no codes showing so im not sure if the coils are gone.

 

Are they just spinning or are you unable to access them? If they are spinning take a thin flat screwdriver and use it to pry lightly as you turn the bolt. At times the slight applied pressure will cause the nut to stop turning. Hops this helps!

 

thanks for the reply Gus

im not able to access them at all...one is the middle bottom bolt its beind the oil dipstick and the other one is closer to the firewall

 

I used swivel head rachet wrench for the rear bolt. I took them off the same time as I changed the cover gaskets so I had the dipstick out of the way, but maybe the wrench might work there too.

The oil in the spark plug well is a sign of failing cover gaskets and insulator bushes. The problem is that the oil may eventually cause a short in the spark plug. I didn't have oil there yet, but generally the covers were unpleasantly oily and I changed the gaskets and bushes as a precaution.

 

I do understand that they are hard to access. Not knowing the tools you are using I use a ¼ in system with a bunch of extensions and universals. One of the best tools I have is a universal socket set in metric. A great addition Sears: Online department store featuring appliances, tools, fitness equipment and more

 

yes i was using a 1/4 set as well...just that i couldnt fit the bit and the wratchet together with the lack of space....i'll give it a try again...i was wondering if i had to remove any other parts to make it more accesible but i dont see how that would happen...the dipstick and the PS pump is blocking the middle bottom and the back one is blocked by some other thngs...

 

What I mean it seems you call them flex head gear wrenches, you would need to a 7mm one though. I find them invaluable in some tight spaces.

 

aah gotcha....i think those should work i'll go grab one today and give it a go

thanks a bunch...hopefully changing plugs will solve the misfiring

then i'll move in to the no heat issue haha its been discussed so much in the forum i was overwhelmed with everyones different problems

 

so i went to get a ratcheting wrench set today...the smallest size is 8 and the damn bolt is 7 haha...i refuse to take it to a shop im gonna figure out a way to get this done....even if i have to use a regular wrench and take 20 mins per bolt

 

AND ITS DONE!! no more misfiring thanks guys for the advice....worked it out in the end

 

So how bad were the plugs?

 

looked like they were from 1969 haha...my fault for not checking when i first bought the car...could have caused bigger problems

 

If it's done, that's what really counts! Good stuff!

 

Just a bit of advice. You mentioned some oil around the plug. With the age of your car I would plan to change the cam cover gaskets and spark plug well gaskets. Most likely you have oil in other plugs as well. So your fix may only last awhile until that cylinder or another starts to misfire.

With a DOHC engine it's good practice to change the gaskets and all plugs/coils at once. As a number of people have found out going back in to change them one by one is a pain! I view this as just normal maintenance for a DOHC type of engine. It is more of a problem for the early cars as Jaguar improved this in the 2003 face lift cars.

As the gaskets age and start to seep/leak you might also start getting an oil smell inside the car. That's because the passenger side gasket will seep oil and drip it on the exhaust manifold. The fresh air intake for the interior is at the base of the windshield on the passenger side. These fumes are then sucked inside the car.
