Disclaimer… I’m not a certified mechanic but I’m fairly “handy”, have a lot of tools and I have rebuilt a few 4cyl gas engines before….
Background, I purchased this 12HT back in 2014 and swapped it into my Hj60. The engine came from a 1988 JDM HJ61 and had approximately 270,000KM’s on it when I got it. I put another 50,000KM’s on it before I started having issues….
Part One:
I had noticed that the engine temps were creeping up over a period of a couple months then eventually noticed that I was losing water.
Didn’t really know where it was going. Oil still looked good and it really wasn’t pushing white out of the exhaust.
Shortly after that, the temp gauge spiked and I noticed it was low a lot of water.
I suspected the head gasket was blown from me slowly turning up the boost and giving’r
I parked it and debated what to do for almost 6 months…
I eventually did a compression and leak down test but it was inconclusive. I ended up ordering an OE Gasket Kit and was just going to re-gasket it.
I pulled the engine and tore it apart. I did not see anything catastrophic. Yes, things were obviously warn but no tell tale signs.
I measured the bore and the crank end play. Things were out to be out of tolerance (to be expected) but nothing extreme.
