[solved] Need help, car heats up on VTEC! But only on very hard runs!

[Bludger]

Great info here Guise...

Well today must be useless comment day...

Let me have go... You must have a vagina because I pee standing up??

Mate way to go commenting on how "someone else" treats their car without ever meet the person or worked on the car...

Anyone one who has even a small amount of knowledge on cars can tell you there's is more than one reason head bolts can stretch....

thanks for having a cheap shot.

I wasn't having a go @ you btw.
I was assuming that you had no idea that your car had head gasket issues while you were enjoying your long drive through national park, all the while spending a lot of time on vtec above 5600rpm.

Basically when ever I go for a nice long drive say through the national park, the car will eventually overheat to the point where the temp needle will be only a few bars from H!!

But this only happens if I spend alot of time above 5600rpm (on VTEC!)

And heres the thing, when it heats up I just back off the gas and if I stay off VTEC as in shift before 5500rpm the needle won't budge from it's usual position and this is with 20mins of hard driving just below 5500rpm.

This doesn't happen when I hit VTEC during daily driving eg: VTEC in 1st 2nd and 3rd, then drive normal ans the repeat, needle doesn't move! But as soon as I got for a long drive hard drive and start hitting VTEC too much OMG the needle starts creeping up!

Note: car does not suffer from any other over heating symptoms eg it can sit idle for 10 years as still be fine, problem is of I spend too much time above 5600rpm!!

If @ the 1st sign of overheating.....

you baby it home and look for the cause.....

headbolts probably wouldn't have stretched.
