Lets hope this is the winner. Brought it to 70ft-lbs last night. The plan today is pick up a heater and heat it up then toque 1 more time....and leak test. |

Didn't remember I had this heater. Box out of wood left from the basement door project...now wait...it already hot in the shop but I'm not leaving this unattended

More improved...ovens need doors I guess. The 1 side was pretty near 200F even all down the head, may by 190 on the block. I moved the heater one last time and got the other sides head and block 195-205 and that's the front so it gets hotter in real life so I'm calling it cooked. It took about 90 minutes, maybe a little more

I tore the box part and retorqued....not sure it had the same effect as a real heat cycle but the pressure caps are on so now waiting for the sealant to dry enough to hold pressure, maybe tonight

I THINK its sealed. Testing continues and I'll probably up the pressure later but I put 15psi of air in and the gauged hasn't moved after 30 minutes. Last time with air 15>0 was about 30 minutes.

I checked at 1 hour, 0psi  upon further investigation the RTV I put on the block-off plate holding the gauge and didn't wait for it to fully cure blew out so there is a large and obvious leak there. I knew I should have waited longer but real wanted to know....so I'll reseal it after work and then wait until tomorrow to repressurize. |

Resealed the gauge plate and its been sitting at 30psi for 30 minutes now The question now is will it stay sealed? The other gaskets never got shipped, sorted that out today but that means engine back in next weekend is the best case

Ferrari specifies pressure testing the cooling jacket after doing the timing belt in the 360. I've seen that procedure around the internet. What pressure and duration do they use before they call it good? |
