on the 2.7 is it just a 2.5 head its on karans old car GUG if anyone knows the engine i need a head gasket an poss a head also is remanufactured heads any good or should i just get a new one and where would be a good place to get one i sound stupid but just trying to learn thanx

GUG used a standard head gasket, so no probs there.

What's wrong with the head, as it's not exactly standard ?

dont no for sure wots wrong with the head yet preparing for the worst just but the head was skimmed
in nov dec and a thicker head gasket used the thickest of three from bmw apparently an she blew a couple of weeks ago on my 2nd day of ownership well i think she blew she went off a cylinder blowin white smoke an mixed haven got a chance to get her tested yet. do u know wot all was done to the head on her as i dont want to lose any power thats why i bought her after all

The head was originally from Griffin Motorsport, and was ported and flowed (on a brand new casting) etc. It was a very nice head, and really needs to be saved if possible.

Ian.

well if its been skimmed to many times it cant be saved can it? im thinkin its been skimmed to much an compression is to high for gasket can u get thicker ones? if i have to get a new head i will buy a new one an get it ported an flowed although the reciept was for 940+vat it would surely be worth it. she was going well to for my one day as she now has a full btb manifold an system

how about cometic? do they do headgaskets for the e30? they do thicker 3 layer steel gaskets to allow for skimmed heads that are re usable but i dont know if they cover bmw's

do they have a website i could look into it thanx

try them on here

looks like they can do anything as a custom gasket but as for ordering one i think i will need someone to do it for me the measurements have me lost an how would u know how thick to get one

what about these ones do u think they could help me

right i can get a decompression plate and save the head bringing compression back to standard all i need is the depth measurement of a standard head can anyone help me with this

Standard 325i head is 125.2mm thick and can be machined to a minimum of 124.7

got the head pressure tested and skimmed this week (good job i have another car this is takin ages ) she now measures 120mm so looks like i def need a decomp plate has anyone any experience with these

i had a 3mm made up from feriday for use on my 2.7 turbo, but i got rid of that engine and kept the decomp plate, ive actually given it to Ant and he might still have it,??

you sure its been skimmed 5.2mm?! Thats a massive amount off!

Get a ruler out an measure it just to make sure. OK not accuaret to parts of a millimeter but will tell you if its 120mm, 123mm etc.

Was at Ants yesterday (thanks Ant for the bank holiday time) working on the Racecar E30/Eaton M90 project and yes he has an ali decomp. plate hanging on the wall.

i wont get over to c the car till wed as i have it at a mates garage an hes away till then i was thinking it was a brave bit took off and def want to measure it myself to be sure. i have loads of new parts to go on and this is the last problem to sort so want everything to be right this time so i can have something sort of reliable!

Blingsta would the plate u had fit mine as its the 2.5 head?

yes it will mate... i had a 2.7 bottom end with a 2.5 head... no probs.. i'll find out if Ant still has it..
