Low oil pressure after front seal change etc.

[aztecair]

Hello VW gurus etc.

My 1971 dual port motor is giving me a fit, I pulled it for an unstoppable front seal leak and did the following while I was in there -

1. drilled a 3/16" hole in the case at about 6:30 position behind the front seal
2. Before I installed the new seal, I cut about 3/4" off of the spring and reattached the ends.
3. Installed the seal ALL the way in to the stop in the case
4. while I had it out, I reset the end play from a whopping .015", down to .004"
5. Adjusted the valves

Sounds pretty good, eh? - Well now the thing is running very hot, and and scaring me to death as I drive it around with the oil light on after about 5 minutes of running - and forget the freeway!

I'm stumped, could resetting the end play have changed the distributor timing at all?

It runs purfect, just hot as hell -

What say you, oh great minds of the Samba?

why did you drill a hole. The case has a drain for the front oil seal already.

As Mark suggested, check your timing first.

Thanks folks - I will check the timing, I tend to agree, and hope and believe this could be my demon !

RE: Why did I drill the hole? I believe the drain slot (passage) to be clogged probably from sealant during assembly - I had changed the seal at least twice and can't stop the leak, so this is my "Hail-Mary" having read a lot of folks doing just that - drilling the hole - GoWesty even makes a tool to do it for type 4 motors, I have to admit it took me a lot of thinking to 'bite the bullet' and drill it - scary, to say the least... I'm still hoping that was OK to do - I'm not in the mood for new short block $$$$

You can not tighten the endplay on an engine with a loose thrust bearing, assuming the thrust bearing shell is loose in it's saddle (which is very likely) if you try and tighten the end play you may seize the crank to the bearing.
