Head Gasket Failure !
For you guy's running high boost . . it's only a matter of time ! the gasket failed at the corner of cylinder number 4. the (2) head bolts at that corner required only about 20 ftlbs. to remove, where as the other remaining bolts required 60+ ! ! take this as a warning ! !

Thats the same area mine was going to let go on!!!
Glad your block is OK !!!
The head is very cheap to buy at dealer cost - you should consider that depending on how much the machine job is
WHile you have it apart you should look into a set of rods - I have a few options for you and AMS (great guys) have a set of JE pistons that work with the stock bore and use stock rings - just slide them in and apply a new set of rod bearings and your done - they are 9/1
Of course - I prefer the Pruven race pistons - I think they have more potential
Either way your 100% better of than with the stock rods which are not up to your useage !!!!
BTW - while you have it out - check out your bearings - it seems the evo is not liking the syntehtic oil - the two engines I took apart both had very bad looking main bearings
I'm glad you are making nice progress and going quickly on this rebuild - - my engine should be broken in within 2 -3 days and then i'd like to race you again - maybe this time you can bring one of dem Enzo's - cause thats about the only way your going to stand a chance !

The AMS guys are the ones who sorted out the stock bore pistons - you can call martin over there - he was the one who got me all the cams - - those pistons they use have stock rings - a very nice choice if you want to stay with the stock bore
For myself - i couldn't resisit the opportunity to over bore it and also get the o-ringed block
Also - I am running a bit more clearance than stock and a lot of ring gap to accomidate the nos application
For the rods you just have to decide which wieght you want - there are three choices - obviously the lighter ones spools faster - the heavier one is mega strong and will be the last rods you have to buy - (BUT the piston and rod combo will be heaveir than the stock - although with the deletion of the counter balance the rotational mass is still a lot less) - Crower takes like 10 weeks - forget that - Oliver is the medium one and that is what most of the guys in the UK use - they are a great company and will prob extend you a trade pricing - they are very reasonable in price and a great rod - the pruven ones are the real heavy weights which are suited to big boost and large nos shots - they are like 200 a rod - also there are TI ones at 370 a rod
All those rods use the stock bearings - you just have to get that EVO shop manual and read the codes off the crank - basically all those rods will bolt in
If you want to hang with me you will be needing that enzo man - I am going off the deep end with my evo and it will be a mid 10- second car by the end of September !
