BMW issue
HI All,
First time poster Hope your all doing well.
Bit of a long story here, but im looking for advice and will try and keep it quick.
Basically purchased a BMW 530i E39 (2004/53 plate) Champagne Edition 2, with a headgasket which had gone - Previous owner had put fuel into the coolant, after a mix up with a watering can at a filling station.
My brother being a current BMW mechanic, and me having alwised fancied a Champagne Edition decided we could fix it - as labour would be free.
After dis-assimbling it it was clear we needed to get the Head Skimmed, which we did, then we had a exhaust cam snap (Quarry Motors Sourced us a new one)
We tightned it down, and the stretch bolts on the exhaust side where loose on torquing - so im in the process of having all bolts heli-coiled.
My first problem is with how good the repair on the block will be - confident with the guy thats doing it, however he cant guarantee the coil will hold in the block - has anyone had any experience with coils in the block. (hes doing all studs to be on the safe side)
My other worry is the head, the guy who skimmed the head has given me 2 differnt answers too how much was taken off the head. Firstly 15FAL (which is allot i belive) then on confirmation hes said a couple of FAL.
I understand the BMW oversized gaskstets are 3FAL above a normal gasket?
SHould i risk putting the head back on, with an oversized gasket, or am i running the risk of the Valves hitting the top of the pistons? The grooves in the top of the pistons seem to suggest the tollerances are pretty tight?
Quarry are looking for a new head for me, however will i just be in the same boat if i dont know how much has been taken off?
Thanks all
Cheers
Rob
