June 22, 201115 yr Author comment_534388 ok so lonsdale engine works let me down and its getting delayed till friday so the car won't be back together till sat arvo Report
June 23, 201115 yr comment_534390 sucks to hear about the delay man but I'm sure with the whole weekend to work on it and ur quality of work it will come back better than before Report
June 23, 201115 yr Author comment_534530 well i picked the head up and it tested ok but they didn't face it.. the head is warped... so he gave me the option... the machinist reckons that with new headbolts and a graphite gasket it'll cplamp down just fine but no gaurantee... but if i get him to straighten it it'll be a full reco and cost 500 ish bucks... so i'm going to bolt it down and fingers crossed she'll be ok if not i've only lost a head gasket. if it work sweet as and i can start searching for my new motor.. 5e.

June 23, 201115 yr comment_534550 if its warped can't they machine it straight or will they take too much off witch will result in 13:1 compression? Report
June 23, 201115 yr Author comment_534560 nah u can face it but it would still mean that te top of the head where te cams bolt to will be warped and the cams will get worn or seize up. Report
June 23, 201115 yr Author comment_534564 so the theory is bolt it down after cleaning it up and essentially bolting it down should flatten it out. and pull the top of the head where the cams are straight as well. its only bent 5 thou so not heaps the ghraphite gasket he thinks is quite forgiving and the new headbolts will help out as well as they are a torque to yeild bolt apparently.. so they'll settly in how they want to. basically i'll give a go if it works then yay.. but i'm now on the lookout for another head in good nick to get cleaned up as a back up.

June 23, 201115 yr comment_534567 or even go new arp headstuds. that should straighten her right out Report
June 24, 201115 yr comment_534817 man be aware you risk breaking the camshaft as well, but i really hope things go well. do you know anyone with an alloy welder? Report
June 24, 201115 yr Author comment_534869 alloy welder? yes but why? the head is bent 5thou top and bottom the idea is that bolting it back down will straighten it out... Report
June 26, 201115 yr Author comment_535261 well all back together and still the same problem... the water is boiling in the head but not in the block... seems like a blockage but its been all flushed... thermostat was suggested but its brand new... i'm gonna gut my old one and put that in see if it fixes the boiling... what i really need is to see another 4e so i can have a look at how ALL the water lines go. and compare to mine.. perhaps i have something plumbed wrong.

June 27, 201115 yr comment_535404 Welder is how they can be straightened, but didnt read properly, 5 thou not worth trying. Did you compare head gaskets? I mean sit down and spend 10 mins comparing every little hole from old to new? I have had a few first hand experiences where mates have had this problem, one diffent hole in hg could cause lots of drama. Report
June 27, 201115 yr comment_535405 i would be VERY cautious about putting a head back on that wasn't straight. even if it is 5thou or whatever, its still not straight.... 5thou = 0.127mm, thats quite significant i would have thought? the $500 sounds about right, they would be re machining everything in the head, cam bearings, valve guides prolly too.... i did my mates head on his 98' 323 astina (huge over heat), to straighten the head, and buy a gasket set...not much change from 1100 bucks. almost replacement engine time. Report
June 27, 201115 yr Author comment_535558 yeah oh well.. its back together and its now running properly well sorta... its not overheating anymore but there is a distinct power loss at approx 4000rpm really annoying.. i'm sure i'll figre it out. Report
