TurboSPFI Posted August 15, 2005 Share Posted August 15, 2005 Well, Ive fully pimped out my cooling system including a headgasket job to find out that I have cracked heads... pretty nasty cracks inbetween the intake and exhaust valves... So, what should I do? I hear brand new loaded heads are about 250$? per side... Should I cough up the 500$ plus whatever it costs to get the delta cams or just run this motor until it dies? I guess the question is.. would it be worth it to get some virgin heads with some new cams? Link to comment Share on other sites More sharing options...
88rxsedan Posted August 15, 2005 Share Posted August 15, 2005 the small crack in between the valves is normal, even with gen 3 heads.. ive seen several cracked with no performance degredation.. could you post a picture of it for further analysis Link to comment Share on other sites More sharing options...
TurboSPFI Posted August 15, 2005 Author Share Posted August 15, 2005 Nah, I've already reasealed my engine... I still have the bubbles in my coolant which I'm almost sure comes from that dept. Link to comment Share on other sites More sharing options...
NorthWet Posted August 15, 2005 Share Posted August 15, 2005 I would seriously doubt that those cracks reach into the water jacket. Generally (speaking non-soob-specific), those cracks bridge the intake and exhaust ports and/or cause issues with the valve seat inserts. Without bandsawing the head apart, I would guess that the nearest that the water jacket gets to the valve seat bridge area is about 1/2 inch... that would be a very deep crack, and the car would show other problems first.

MorganM Posted August 15, 2005 Share Posted August 15, 2005 Yes I would suspect cracks somewhere else. Not between the valves like you noticed but rather deep in the exhuast port where they actually can crack into a water jacket. Cracks can be hard to see with the eye. I have heads pressure tested by a machine shop to see if they are realy cracked or not. Link to comment Share on other sites More sharing options...
Steveman09 Posted August 15, 2005 Share Posted August 15, 2005 When I rebuilt my EA82 I too had the big cracks between the valves on both heads, I then ported the heads out even bigger and had them pressure tested to extreme PSI and they passed with flying colors. No problems. Link to comment Share on other sites More sharing options...
TurboSPFI Posted August 15, 2005 Author Share Posted August 15, 2005 Dang, the things I should have done BEFORE I resealed the motor.. oh well, I was on a timeframe. Link to comment Share on other sites More sharing options...
NorthWet Posted August 15, 2005 Share Posted August 15, 2005 BTW, you might want to consider getting rebuilt heads. CCR is an option, as is at least one place in the Seattle/Tacoma area and at least one in Portland, Oregon. The semi-quote that I heard a year ago for turbo heads from a local rebuilder was around US$230-250 a pair. (Don't know about SPFI, but should be nearly the same price.) By the time you pay to pressure-test, surface the head, and do a valve-job, you are probably looking at more than that cost. Link to comment Share on other sites More sharing options...

NorthWet Posted August 16, 2005 Share Posted August 16, 2005 I'm not talking about rebuilt. I understood that. I was offering up rebuilts as a very viable option. Link to comment Share on other sites More sharing options...

MorganM Posted August 16, 2005 Share Posted August 16, 2005 I hear brand new loaded heads are about 250$? per side.. Where did you get that quote? All the $200 to $300 heads I found were remands. I paid about $400 for a brand new one from SOA. Link to comment Share on other sites More sharing options...
