TRB-001 Posted June 6, 2009 Share Posted June 6, 2009 lol if u havent pulled a engine apart before i would not be attempting it on your own car if u still want it to run (no offence) the first tool ull need is the workshop manual..... look around and it tells u step by step of how to do it....reason being wen u pull your head off your not just undoing a few bolts and bam..... ur pulling off your exhaust, ur intake, ur timing belt and about 70% of all the bolts on the engine. and yes there is a certain way of undoing and retightening the bolts...

Stealthynsa Posted June 6, 2009 Author Share Posted June 6, 2009 Has it cracked a headgasket or been overheaten? there is nothing wrong with the head never had trouble, he just said when ever u take a alloy head off a car it always needs to be milled so yeah is he talking rubbish to get me scared and take it to him Link to comment https://www.sau.com.au/forums/topic/273428-rb25-head-removal/#findComment-4640444 Share on other sites More sharing options...
MrStabby Posted June 6, 2009 Share Posted June 6, 2009 I'd be trying to get that bit out without pulling the head - have you exhausted all options? Re: machining the head, on cast heads you can use a straight edge and feeler gauges to measure how out of straight it is. There should be spec in workshop manual about how much is ok without machining. I wouldnt imagine that alloy would be any different, but i'm sure the workshop manual will have the info.

SATO GTS Posted June 6, 2009 Share Posted June 6, 2009 have you tried to fill the cylinder with oil @ BDC and turn the engine over by hand and hopefully the oil will push out the bottom of the plug? Worth a shot instead of pulling the head off. Link to comment https://www.sau.com.au/forums/topic/273428-rb25-head-removal/#findComment-4640789 Share on other sites More sharing options...
blind_elk Posted June 6, 2009 Share Posted June 6, 2009 have you tried to fill the cylinder with oil @ BDC and turn the engine over by hand and hopefully the oil will push out the bottom of the plug?Worth a shot instead of pulling the head off. Piece of string or thin rope, coated in grease. Stuff it into the cylinder, bring the cylinder nearly tp TDC, the grease should pick up the broken bit of spark plug.If you must pull the head, do a search for the torque specs and remove / install order.

urtwhistle Posted June 6, 2009 Share Posted June 6, 2009 is it the steel part or the ceramic part? if its steel- I'd be getting a small magnet on a wire or rubbing a screw driver on a speaker magnet and then putting it down the spark plug hole. and hopefully u pick it up.

Stuff it into the cylinder, bring the cylinder nearly tp TDC, the grease should pick up the broken bit of spark plug. That's a damn good idea. Hopefully I'll never have to use it, but I'm going to throw that one in the old bag-o-tricks for sure.

PM-R33 Posted June 7, 2009 Share Posted June 7, 2009 (edited) If you do decide to take the head off. then to do the job properly you will need: Workshop manual (Most important thing, without it don't bother because you will need all the torque settings) Harmonic ballancer puller 10mm allen key socket. Full socket set and all your basic tools Torque wrench Razor blade (to get the old head gasket material off the block) Headgasket (or just get a VRS kit and do all your seals and gaskets while your at it) Deck the head New head studs Engine Oil Coolant If you haven't done your timing belt and idler do that at the same time. That's all i can think of for the time being.

MBS206 Posted June 7, 2009 Share Posted June 7, 2009 I have a copy of the workshop manual too, if you want a copy, PM me your email address. It's an electronic form (PDF) As to the plug tip, if you've started it since then, I'd actually be pulling the head. There is a HIGHLY likely chance you've f**ked the bores, or a valve.
