The pressure inside the coolant system can become higher due to compression gases escaping from the compression chambers into the coolant system. Hi Steve ,cracked heads and blown gaskets often have symptoms such as a cappocino like froth on the inside of the Oil filler cap.

I would take it to them for a diagnosis, and then deal with it. You can do a leak down test, and a TK head check test. Register to remove these Ads! I'll go put it back together and run it with the radiator cap off. Can you get the head X rayed? What kind of money would I be looking at to get the tests done? Maybe pulling the dodgy plug for a look would be the obvious answer. I couldn't get the glow plugs out cuz all the injector pipes were in the way of my spanner. It doesn't blow any white smoke that I've noticeddoesn't lose coolant at a great rate of knots, and the oil and water are fine not milky. It's getting progressively more difficult to start though on cold mornings, I know one of the plugs has dragged the others down, but seeing this has got me worried. Also had my buggered radiator replaced by a specialist, who ran a pressure test when he replaced it and said it seemed fine.

Not long after that I went to another mechanic for a chat and he reckoned if it was cracked it would spew coolant when you pop the cap off the radiator when it's hot - it doesn't. I had been told by Toyota a while back that they had detected a fault in one of my cylinders, and they suspected it might be cracked. of 2 1 2 Last Jump to page: Results 1 to 15 of Add Thread to del.Ĭylinder head buggered?

Still the fact is the same thing happens to genuine heads very often but thats an interesting thing about the "plenty of engine builders have shyed away from STA heads" I would not be surprised really I guess so maybe in this case thats all it is. In this case it isint the cleaness or conditon of the cooling system thats for sure! as the litttle radiator was checked, cleaned & flow tested and the main radiator was re-cored with a brand new core also at the same time an aftermarket trans cooler was fitted and the viscous fan is in good condition. I can not comment on how it was driven as I was not there 99.9% of the time but I don't think it would have been thrashed or driven in a stupid way as the guys not like that but only he knows I guess. Thanks for the replys few good insights and ideas.

I have done quite a few head swaps or repairs on them over the years, but recently I have been completely amazed by how crap they are again as about two months ago a freind was looking at purchasing a mid 90s Super Custom with 160 odd kms on the clock which had major head work done 3000+ks ago with just under $4000 worth of receipts from a reputable workshop for brand new STA(Chinise) head and all the related common things, I went with him to look at it, we did coolant leak/presure test, compression test and few other checks and motor acted like new, everything seemed legit like reciepts, records, kms etc so he purchased it and he even got me to do a EGR removal after he got it as thats a rumoured problem with these motors.Īnyway now fast forward to last week which is about 4-5000kms later he went to do an oil change an at the same time he checked the coolant an it was down by 700 to 1000ml so he toped it up then decided to check it a few days later, it was down again, was presurising the coolant system on free rev, so we took the head off, got it checked, it was soft and had a mild bow/warp in it! yes ive looked at everything related to the block that you can do in place like checked its flat with a good strait edge, looked for any damage anywhere etc and it seems mint. Its pretty well known that the Toyota 1KZ-TE 3L turbo diesels are pretty average when it comes to reliabilty in the head department but does any one know why!
