OK This on has me stumped.

Can anyone here provide more insight?

Details:

Broke a TODA Timing Belt (stay away this is the 3 time) ALL of the valves; bent.
Replaced all of the valves and had a valve job, all new OEM seals.
-reinstalled the head.
*** Resulted in all the ports on the intake and exhaust side leaking oil.

This time I pulled the head and had new guides installed and another set of Seals
in (Ferrea)
- Reinstalled the head
*** Resulted in the same thing!

Now some other notes:
- plugs are perfect.
- Tops of Pistons are clean and not oily
- Chamber is clean and not signs of Oil

I am completely stumped. I am going to do a leak down, however this will only show the seal capacity of the valves and the top compression ring.

Anyone with other ideas here ?

 

hmmm weird, maybe the machine shop keeps messing up on the install of the seals. Thats the only thing I could see a problem with. maybe too much crankcase pressure? I don't know without more info.

 

Leak Down Test was good. only 3 cylinders were @ 0 and 1 @3% loss.

Still good either way
