Oil Pan Gasket Replacement

I have several leaks coming from my oil pan on my 86 CJ7 258 I6. Before replacing the gasket are there any special things to be aware of?

I notice that the gasket only covers about 3/4ths of the oil pan and then the gasket for the timing cover comes into play.

This is my first Jeep and is it worth replacing or are they prone to leaking?

Thanks Bob [img]images/graemlins/blush.gif[/img]

Re: Oil Pan Gasket Replacement

Hi-ya!
In my opinion,yes it's worth it to change this gasket.
One thing I would recommend doing is before you
unbolt anything,take it to a self-serve car wash and
clean the heck out of the bottom of the engine,then
let it dry.Then drive a little and check out not only
the places you think it's leaking,but if the front and
rear seals are good,and if there is any leaking from
above the pan.If you change the pan gasket,now is
the easiest time to do the seals.And a Chiltons or
Haynes manual is handy to have if you don't yet.I've
used a torque wrench on even the pan bolts with
good results.Tendency to Gorrila torque here.And
more questions can be asked here if there is any
uncertanty about seal proceedures.Good wrenching!

spring for the 1-piece gasket, trust me, it's worth a few pennies more.

Do the rear main while you're in there. It only takes about 10 minutes more if that.

I believe the 1 piece oil pan gasket is for the 4.0L so that is the application to ask for at the parts place.

Re: Oil Pan Gasket Replacement

Yup...1-piece is the 4.0 gasket. Far superior piece...put one on the spare engine for my '86 CJ-7. Definitely do the main seal at the same time, and you may even want to get the extra mile and do your timing set.

Re: Oil Pan Gasket Replacement

Thanks Guys,

I just ordered the "1" piece gasket which I wouldn't of thought of without your help. I will replace the valve cover gasket at the same time. Two things i hope to mark off my to do list!

Re: Oil Pan Gasket Replacement

Although anything is possible ....Odds are it is not your oil pan gasket unless someone has replaced it since the factory did. Mine was on there so good I needed to use a spakeling knife and a hammer to get it off and this was upside down on an engine stand.
the one piece gasket can also be had at Autozone, it is a Felpro gasket.Shipping charges ar legalized robbery from these mail order houses
