Over tightened head = this......	Sat, 16 April 2005 08:07

I am in the process of doing some mods to my 7MGTE powered Cressida (bigger cooler, turbo, intake manifold, computer etc.) Before I pulled the car of the road to do these mods it was starting to develop a overheating problem being a 7M the first conclusion I come to was BHG but I checked everything ells out first and nothing fixed the problem.. So while the car is already in bits I thought it would be a good opportunity to check and replace the head-gasket.. While I was pulling of the exaust manifold I noticed a water stain down the side of the block I thought maybe the block had a crack in it and this was causing my overheating problems but wasn't 100% sure because I couldn't see a crack so I continued pulling the head off when I found this!!!!!!!!!! The headgasket hadn't actually blown which was probably thanks to the o-ringed block but i guess that doesn't matter when there is a crack down the side of your block leaking water out.. I rang up the guy I bought the car of 2 years ago and questioned him on how tight he did up the head bolts and he told me he did some research and did them up to 90ft/lb Toyota's specs are 60 and most people say to do them to 72 just to be safe but not bloody 90!!!!!!!!! So if anyone has a 7MGE or GTE block laying around please let me know as I am now on the search for a replacement [Report message to a moderator]
