Evan Purple240zt Posted July 12, 2001 Share Posted July 12, 2001 Hey guys,heres the deal. Found the oil leak. Its leaking between the top of the front cover and the head. I dont have any breather hoses hooked up, so there is no vaccum in the crankcase. It only really starts leaking when the engine is being revved. I assume this is NOT normal, and i need to switch headgaskets. Not what im lookin to do. Are the ARP head studs re=useable? I only have about 20 miles on the motor and CANT afford to replace them. I am afraid to keep tightening the bolts in the front cover, id really be SOL if they stripped out the holes!!!! Anyway, i guess if there was a hose hooked up to the intake it wouldnt leak. But wouldnt this be more of a bandaid fix??? Help me choose the right path guys, i gotta act on this like asap! Thanks= Evan PS.. i did figure out the pinout on the delco alternator and it works great! Quote Link to comment Share on other sites More sharing options...
Ron240zxt Posted July 12, 2001 Share Posted July 12, 2001 Ok Evan im confused, why do you have to replace your headgasket. Let me understand this. A: its leaking between the front cover and the head. So basiclly were the two 10mm bolts are. B: Next question when you built your engine did you stick the screen back into the engine were the block breather was. This prevents oil from splashing up and out of the breather tube. c: Whats the pin out Dude i need the knowledge man PLEASE Call me....Finishing it tommorow.. I figured Battery/Ground and the T is ?

blueovalz Posted July 12, 2001 Share Posted July 12, 2001 Perhaps I've missed something, but is there not any place that a vacuum signal could be ported to on the block or valve cover to act as a PCV set-up??? Quote Link to comment Share on other sites More sharing options...
Evan Purple240zt Posted July 12, 2001 Author Share Posted July 12, 2001 yes, there is. However, i will be sucking air right through the leak in the gasket. Honestly, will this cause any problems? If not, ill just hook up the pcv and look the other way! evan Quote Link to comment Share on other sites More sharing options...
blueovalz Posted July 12, 2001 Share Posted July 12, 2001 Ideally, the vacuum signal ported to the block or valve cover will draw air from another open fresh air (filtered) source located elsewhere on the block or valve cover, through the block and into the vacuum port for a continueous but small flow of air. Any blow-by would reduce the fresh air flow by replacing it with the blow-by. Surely the leak or gap at the top of the chain cover is not very big.

Evan Purple240zt Posted July 13, 2001 Author Share Posted July 13, 2001 Yes, the main breather is filtered of course. The leak in the front is SMALL, and the amount of unfiltered air drawn in woould be very insignifgant I think. Thanks terry, and ron.

But wouldnt this be more of a bandaid fix??? Evan... I must be misunderstanding something here. How would using the same PCV setup that the factory used be a bandaid fix? I'm assuming you meant a hose from the valve cover breather to the compressor inlet, and also the hose from the crankcase breather to the PCV valve in the manifold? Seems to me like less of a bandaid than the filter on the valve cover, and no PCV. What am I missing here? The only problem with the PCV system is the possibility of spewing oil into the intake, but this has already been discussed. Also, the ARP head studs are reusable, as far as I know. The instructions for them discuss locktiting them into the block as an option, so that sounds fairly permanent to me. Is there some reason you can't use some sort of sealant on the front cover/head interface?

Evan Purple240zt Posted July 13, 2001 Author Share Posted July 13, 2001 Tim, my point was that just hooking up the breather hose straight into the intake would be a bandaid fix, because i would then be sucking air right through the front. I want to do a setup like yours, but dont have the time or money right now. Probally soon though What do you suggest for sealent? I dont think its an option because nothing sticks to oily metal LOL. Thanks- evan PS.. even WITH the PCV setup hooked up im spraying a bit of oil through the front. I dont get it. How does this happen? I cant belive the crankcase pressure gets that high!!
