Well, it's been 4 and a half years since I rebuilt the engine and ever since, it has taken the abuse I've given it like a champ. High EGTs and 87 octane fuel was the order of the day. It took it like a man. Compression was perfect across the board, and everything else was good to go. Well, you know how they say that you shouldn't have sexy time in your car because it jinxes it? Well, I think that actually is true, because before breaking a piston the first time, my car was the place of some love encounters with my girlfriend, LOL. It can't be coincidence that it broke again after I disrespected it with my current girlfriend. Blown tires and some other things happened before, too.
Anyway, the last straw that broke the camel's back was a 15 PSI test run after tuning it with the eManage. We were gonna take it to the dyno to tune it at that boost level, so we needed to test if the engine would hold or if it would blow like a grenade. Too bad I forgot I had moose piss 91 octane watered fuel from a gas station I never go to, but I had to this time because I was running low. I thought I had Shell 93 and well, nothing made a sound. I nailed it from a dead stop, it just roasted tires with the 17s, put our heads against the headrest, and then coolant was all over the windshield when I let go the gas. Good times. The auto tranny is holding well. No signs of slippage or anything. I ordered a Cometic headgasket and should be here this week. This engine can sure take some punishment. I need to up the boost to see if a rod gives up before a piston. I need an excuse to install the Belfab rods and some other pistons I found. -------------------- |

Hmmm. I'm not going to risk it. The guy explained me how the headgasket works and the reason why they cover the jackets some. I'll just use an OEM one. Besides, it broke not because of the boost, but because of the detonation, because I boosted 15 PSI before with 93 octane fuel and it was fine.
I noticed this headgasket was very rusty also. I found out it wasn't a Toyota OEM one. I'm gonna buy a spare head and order a custom headgasket from Cometic. If this OEM one fails, I'll have the head ready to go with the good headgasket. -------------------- |
