Sounds like your valve seals dropped. I had that happen to me on a Turbo Z once, unfortunatly the only fix is to pull the head
The valve seals have nothing to do with the valve being kept open. Maybe you meant valve guides.Garret said:Sounds like your valve seals dropped. I had that happen to me on a Turbo Z once, unfortunatly the only fix is to pull the head
782? Did your car come with a 445? Just want the same part number put back on is all. Hey take pics when it comes off, never seen a head lose 2 at once yet. Should be UGLY, but impressive. Don't get a TBI though, make sure you find a turbo head. Happy hunting :thumb:Xplizit said:there doesnt seem to be any coolant in the oil. the overheat may not have been that bad. but the 2 valves ARE stuck open. the HG doesnt look bad either so maybe the overheat isint bad enough to crack the cylinders. im going to try to fin another head today, maybe try to find a 827 head.![]()
Exactly, anything can be fixed, its a case of how much money you want to spend. Our local head shop does some nice work on otherwise junk heads. They could have fixed my cracked Lotus head but the money they wanted, I can wait and find good one.moparzrule said:My seat dropped in my ported G head, I sent it back to turbo dynamx to be fixed and he did some welding and installed a .001'' oversized seat. Works great now. Point being a dropped seat(s) is fixable, however not cost effective on a stock head. I had $700 invested into my head so I had it fixed!
It could if the valve seized in the guide,The Pope said:OMG people, the guides don't effect the valve staying open
PTT said:A Florida cracker shadetree mechanic once told me I had the dropped valve guide on the #2 valve because of over revving the engine (1991 2.5L TBI). Made sense to me as the previous owner had a 16 year old son who thought it was cool to floor the gas pegal and dump the clutch. It had the #2 roller laying in the oil valley and the valve guide had slipped down and was holding it's valve down/open. I had a 1993 head that I swapped out and it's been running great since. Still have that original head and I always wondered what would be involved with getting the valve guide back up into the head. Would the valve itself need to be removed in order to tap the valve guide back into place or is the valve guide ruined and have to be replaced??
Xplizit said:so what im hearing is i should find a replacement head in the pick-a-part then. i dont have huge money in this head, but i do have a lot of money into this car now. and i want to keep any further costs down. pick-a-part wants $50 for a head.. if i take it off myself.providing i can find the right one. but there are many to choose from.
Ray Monk told me if i could find a 827 head that would bolt on and flow better.... i might just try to find one. what years did the 827's come on???
