So you ported the valve like I said huh. I figured that would help your problem. Now just fix that front cover and you'll be all set... The seal probablly blew from all the high oil pressure.
Are you serious JIM. Mitch makes a good point oil pressure wont blow a seal out crankcase pressure will. There is no oil going to the seal so there is no pressure on it from the pump like the bearings see. What I would do is stop waisting your time and replace everything including the front cover if you still have a problem. Use all new gaskets and seals and should be fine.
Thanks Mitch for the long post always a help. (sounded kind of pissed) :D

WOW ok, hang on now.. Let me say that one more time.. WOW..

Get a grip guys LOL.. He ported the housing and the oil pressure is normal, no big surprise there. I was making a gross over-generalization with that statement. It's probably more likely the seal was faulty or installed incorrectly which is why it leaked before and doesn't now.

The whole point of what I'm talking about was just to lower the pressure by porting not if the high pressure blew the gasket out, so NO I'M NOT SERIOUS :mad: And if you want to know if too high of oil pressure is bad just ask Marco, he'll let you know.
 
Ok, thanks for setting my stray thoughts in the right places. I dont dispute what the wiseman guys say, so most of what you guys say I pr Im working on getting a 'real' mechanical gauge in the very near future also.. LOL! I know how 'inaccurate' the stock gauge is, and is almost as good as nothing, but it at least shows that I have something flowing. But either way, you're one of the few people that I know, let alone heard of that calls customers to make sure that they're satisfied/happy with the work that you produce. :thumb: Good customer support as well, and flexible. Anybody who lives in Illinois or near Chicago should consider this shop for having an engine built. Im just trying to get this motor perfect because I dont trust many people around where I am to touch my car. They wouldnt understand any of the problems that I have, let alone why my 4 cyl has a harder lope at idle than their v8. I asked one shop here about maybe doing some work on my car and he said, "Its hard enough getting them to run right, let alone ones with performance parts." I dont think its "difficult" per say, but definately labor intensive.

Hey JIM I am just poking at you is all sorry. You did say in your post that the oil pressure blew the seal out and thats all I was questioning. This thread did get a little intense!!!
I agree with you high oil pressure is not a good thing and need to be addressed. I have not done the mod yet but I know I need to get it done. What oil preesure do you see @ 7K??? I would like to be 85 maybe 90 psi as of now I am over 100 psi.

I’m not pissed it’s just the “too high oil pressure” thing that makes me crazy since I know what’s in that engine. I just hope it’s not the leaking because the groove left by the old seal is too deep and I missed that but I don’t think so. Reuben is almost as stubborn as you are and he likes to do things the hard way. Just kidding. I’m just hoping that he works these things out as soon as possible and get to enjoy his car. He has a nice block and it wasn’t free so it’s time for some fun too.

Jim is right. Excessive oil pressure is almost as bad as insufficient oil pressure and it should be addressed. Unfortunately it not something that is easily done because not all engines are the same. To successfully accomplish the task, at least 2 accurate gauges are needed (oil temp and pressure) and an extra pressure one in the head is desired. And maybe some oil filter housing gaskets because it should be done step by step working your way up until the right pressure is achieved.
 
I am a stubborn SOB. You just need to knock me along side the head sometimes. WTF

The bearing clearaces are on the loose side but thats fine on a high HP engine that sees high rpms like ours do.
I thought you said those clearances were different than my "american v8 motor clearances" ??
 
Stock V8 motors normally do have looser clearances than stock import 4 cylinders. Race 4 cylinder engines that will see high rpm will run looser clearances to keep the oil temp down. With the use of light oils now in all motors today all of or motors are built tight at the factory. I was refering to V8s of the 80s in the first post. (did I get myself out of that one)?? :coy:

I didnt say you did anything wrong by me being suspicious of my oil pressure being high, or at least, me THINKING my oil pressure is higher than normal/desired LOL! Im not that stubborn, I do pretty well at taking suggestions, especially with DSMs. I havent been around them for very long and there is much to be learned. Im slowly working all these problems gone and damn right the motor wasnt free!! OMG Deep groove? I dont think you did anything wrong, I am proned to making mistakes. We'll see in a couple days after I get this front main and gaskets assembled. I can only work a few hours a day at it. I work 9 hrs a day for almost nothing$$ :notgood:
 
Ok, thanks for your patients everybody, including Mitch, whom I will be speaking with shortly this week. I just replaced all the seals, the pump sprocket seal, the castle plug seal, and tightened an oil pan stud...waallaaa... :) No more leak, and a car to drive now :D
 
What should I expect for oil pressure @ 8,000-8,500 RPM's. Basically I need to know what is too high? Thanks.
