I did a compression test and found the middle cylinder on the driver side, I don't know what number it is, has a valve issue. I have 30 psi on that cylinder and the plug was very fouled. The other cylinders were all 160-170. I'm going to be fixing that first and then I'll be replacing the lower...

blkhwkns, Thanks for your advice. After reading much more on the topic your advice was pretty much the way I was thinking. So I think first I'm going to do a compression check just to verify that part. While doing the compression check I'll find out the status of the spark plugs and see if I'm...

I'm thinking more along these lines. Don't tempt me I'm so close to the edge...

Well I'll repeat what i said in my other thread which nobody cares to reply to, I am leaking coolant externally which is probably why I associated the smoke last night to white smoke as I could smell coolant. I am also blowing what smells like burning oil smoke from the exhaust. It does get...

Nobody has any advice huh? Ok well I have narrowed down my symptoms. I smelled burning coolant because I am leaking coolant externally. I have smoke from what smells like burning oil in the exhaust. So I either didn't get the lower intake manifold or the gasket seated properly AND I have some...

It didn't sit for 24 hours it was probably 12 at best. The PCV valve seemed fine, it rattled, when I installed it a few days before. When you say blockage in the recirculation system you mean oil not coolant correct? Doesn't really matter though because after I put new oil in and installed new...

I've changed a lot of oil but I have never seen what I just saw. Has anyone ever seen oil start to smoke as it drains from the oil pan? I dropped the drain plug and the filter and at the end of the drain thin wisps of smoke started to come out of the drain hole. This was done on a cold engine...

Oil leak fixed now burning coolant Is there no end? The oil leak has apparently been resolved by replacing the lower intake manifold gasket. It appears I didn't cover the area between the heads along the block with RTV well enough when I replaced the heads originally. I'm not sure why I didn't...

PJM I talked to my ex-father-in-law who is a Ford Certified Master Mechanic you can read about what he has to say about it here http://explorerforum.com/forums/showthread.php?p=2154108#post2154108 Good luck.

Master Mechanic advice... I thought I would share some information I gathered from my ex-father-in-law who just so happens to be a Ford Certified Master Mechanic. He claims the Chilton manual is "full of $h!t". His claim is that he has never torqued the intake prior to torquing the heads and...

Yep I remember. Thanks. The part I dread is the gasket kit, ouch.

Where can I find a replacement for my 94 Explorer? I would rather not have to pull one from a junk yard motor. Thanks.

Read the manual? In my quest for knowledge about my leaky engine I found a post by PJM who was inquiring about Head torquing sequence on a 4.0 OHV. The Chilton's manual states to torque the intake to the heads then the heads then the intake then the heads then the intake again. I am pretty...

Lesson Learned? I just re-read the same procedure. I wonder if that's were I went wrong on my X. I replaced both heads on my '94 4.0 OHV about 5K miles ago. In my haste to finish the job I must have missed that order. I torqued the heads first. I have had a significant oil leak from the rear of...

Was getting ready to tear the transmission out of my 94 Explorer for a rear main oil seal replacement and decided to look into possible other causes of significant oil leaking from the rear of the engine. Might not tear into it just yet. I replaced the heads about 5K miles ago (both had cracks...
