Really not looking forward to pulling a head off ... >.< ... haven't even been able to find a replacement rev1 3sgte head. Mind you I can't say I've looked very hard yet either.
 
Don't suppose anyone has one laying around, that would be able to be purchased.
 
Could possibly do some swapping... I have a complete 3sge under the house, and an E153 in pieces (minus diff).

Here are some spare 3sgte bits for sale. In NSW though.

You might just need to skim the head surface and pop a new head gasket on.

Nice link, sent an email to find out what revision the engine is from, and what kind of price he is chasing.

I was looking at this one point:

As they say, worst thing that could happen is you spent $100

Anyone in Brisbane area used Murray Walker cylinder heads before? ... had a chat to them today after dropping a rally Evo off to a performance shop next door, the guys inside the shop said to have a chat to him...
 
Considering he has a few 3sgte heads in there, and seemed rather knowledgeable ... was wondering if anyone here has used them before, and if so ... how was the work?
 
Was wondering as the rough price he quoted me was "too good to be true" ... being on the very low end for a recondition, however this was very vague, and without seeing the head itself.

Any chance you want to share this 'too good to be true quote'? Just for interest sake?  Did he say much about the 3s heads he's been working on and what sorta work is being done to them?

for a common recondition (inc pressure test) was $300 ... cheap as I figure ... but $1500 for port n polish also ... that part seemed pricey to me.. so was thinking about grabbing some cams.. and possibly giving him the work.. also looking at water injection.
 
Might also add that was an unseen quote ... and nothing on paper ... just talking round figures.

"A common recondition for $300"
 
A couple of years ago I had a 'common recondition' of a 3SGE head reco that cost about $600 (dealing directly with the machine shop)
It involved a crack test, gasket surface dressed, new valve guides, seals, and valves lapped.
I thought the cost was reasonable for the work involved.

I have been there and done that. Changed the thermostat, radiator cap, bled the cooling system. No loss of water or any exchange between the oil & water
I did a compression test and a leak down test. Car ran fine other than overheating when you got stuck into it.
 
The answer........................The head was warped yet this was not revealed by the tests undertaken. This took 12 months to resolve.
 
I didn't think this was possible given the engine had been rebuilt in the last 12 months. One of the thermo fans was not kicking in properly.
 
Lots of luck

I've had it at, and slightly over, operating temp ... parked and watched under car for several minutes both with car on, and right after shut off, so I am fairly certain there are no leaks (even heater hoses will drip onto the plastic undercover and out), and I have a compression tester arriving sometime in the next week, so a pressure test will be my next test, the if that all checks out, Ill rip the radiator cap off the N/A and test that... but if I still can't find the problem, Ill be pulling the head off...
 
While It's off I will also be looking at doing some work to it (cams, springs, possibly a port n polish depending if I can find someone to do it cheap enough). Was looking at some Brian Crower cams, but was also advised to look at Camtech's gear, from what I have read of the receipts the engine has full forged internals (will confirm if / when the head comes off), the better it looks ... the more work I may do before reassembly.

Anyone know the differences in bare head, from 3sge to 3sgte, both 1990. Was wondering because I have a spare 3sge engine sitting, wondering if I can build the head for it to drop on the 3sgte .... unsure though, if the chambers and valves are the same size though... just thinking about options.
