supra head gasket questions+ rebuild

[Andy C]

been reading ddcsme post on head gasket repair and read the bit about
cam position sensor, not sure where this is or quite understand what i have to do with this, is there something im missing or some more i should know before removing the head, many thanks Andy

[Andy C]

phew!! got the head off today, left the cam position sensor on but still unsure what to do with it once i remove the cams i.e timing it up?

right so now i need head bolts and a new gasket and some servicing to the head. any recommendations for parts would be helpful.

not sure how to get the valves out either or what to expect.

still im extremely pleased about getting the head off heres a few pics of todays efforts.

Don't remove the cam shafts. Or the valve covers.

DO, remove the air intake and plenums.
Remove the fuel injection parts. Just don't crack into the head.

BE careful where you and how you sit it. Keep the place clean and flat.
DON't drop it.

Your machinist will want the head and cams and all of that.

You should probably prepare for a valve job. Again your machinist will let you know.

You want to remember how much he shaved from the head also so you can use that number to figure your mhg thickness.

Now..., Start checking all of your antique stock hoses. Especially the ones for the coolant system. Get rid of all of those ancient stock hose clamps.
Get worm clamps and wratchet those bitches down after replacing the hose.

You may as well replace your starter while you are here. Never again will it be so darn easy.

Port and Polish that head. You"ll be thanking you later for doing so.

well took the head down to the machine shop today he told me the bottom end on these engines are weak and dont last long is this true?

gonna leave the rest today tired worked on it everyday since i got it last week, pick up where i left off next week, still got cambelt to remove.

the cam position sensor, i took off the back cover and marked the inside so i know where this goes when the cams go back in, think i leave the adjuster loose until i get the new cam belt on. think this is right.

anyway time to

laters.

just phoned toyota for a gasket set, they quoted me 230 quid for a full gasket set ouch!

the gasket set was 167 quid and 50 quid for the head gasket, im thinking of buying the head gasket from toyota but the remaining gaskets i.e turbo, manifold, plenum etc elsewhere. does this seem ok.

only the american ebay site has a selection of gaskets. the uk one has nothing really, very odd.

another question im afraid. The plate that sits between the 2 rockercovers what is this, mine looks really
worn and peeling? its the one thast sits over the top of the spark plugs.

The cam belt is called the timming belt.

That compartment has to be clean enough for the virgin mary to eat out of.
You don't even want to touch that belt much.

And that gasket set will NOT have every gasket in it you need.

thanks for reply i know the cambelt is calledthe timing belt did i mis spell something?

im aware of the gasket set wont include all gaskets, i iknow the turbo oil pipe will be missing but not srue about the others if you could tell me what they are would greatly appreciate it.
regards Andy

Don' buy a head gasket from ebay. Why don't you try buying the gaskets from a US shop. The exchange rate would treat you very well. Try Jeff at Champion toyota 1-800-327-2087 and mention the forums and the guy from Loxahatchee. They are a toyota dealership and they give the forums great prices.

I have a 91 turbo and tried once to replace the cylinder head gasket. I removed the turbo charger, intake system. removed the 14 head cylinder 10mm bolts, but the head won't come off. Used a rubber hammer to bam it from the side, but won't help. Finally, I put them all back.
Can someone tell me how to remove the head safely?

[supramacist]

Well..., the guide pins are working then. Since you're smacking it about from side to side.

You take it lose..., sounds like you have.
Means you have already locked yourself into machining it again.

Chuh..., You need to start your own thread so we can help you so bill can work in peace to get andy up and running.

And when you open your own thread. ELABORATE...., on and in. Detail.

Help us help you.
