Re: Motor trouble or something

["Dennis C." <dennis.2914@xxxxxxxxx>]

Probably not your problem but I had a serious oil leak on my 383.
Worse I fought the problem for a long problem until I found out what I
had done wrong.

When I put the engine together I put the wrong breather cap on the
valve cover.  I installed a non-vented cap instead of the correct
vented cap.

It resulted in failed valve cover gaskets due to the vacuum in the
engine and eventually cracked the valley pan in a couple of places.  I
had oil everywhere and I suspect if I had been running regular oil
instead of synthetic I probably would have had a fire and lost the
car.

When I pulled the intake manifold I found the cracked valley pan.

I ran a compression test prior to pulling the intake because #7
sparkplug was fouled with oil.  Compression was much higher on #7
cylinder.

I found the intake sealing part of the valley pan was leaking at #7
and allowing oil to be pulled directly into the cylinder.  I had
installed the valley pan they way I found it when I pulled the engine
down, no fiber gaskets, just the metal valley pan.  When I put it back
I used the valley pan directly on the head and a fiber gasket on the
intake manifold side.  I used "The Right Stuff" gasket sealer between
the valley pan and the head

This has been several thousand miles ago, the oil fouling cleared on
#7 cylinder and compression is back to normal.  I have  not seen any
evidence of an oil or vacuum leaks with the valley pan.

I doubt this is your problem, just an example of how a simple mistake
can become very serious.

Good Luck

Popped hood the there was oil all on the passenger side header gasket area and looked like it was coming from cap and somewhere else. I noticed when I start it now, theres a loud "suction sound" comin from back I motor that increases with rpm. I checked vacuum lines etc and found nothing. To make matters worse, I went to clean headers not thinking and now my nice silver ceramic tti headers now have blue melted spots where rag touched. Oh Friday 13 how I hate thee. I have the worst luck with cars I swear.
