View Full Version : big problem
hi guys
well after 3 day of the 5 being road bound it went pop.
i was in 5th at 5500rpm
afr's at 12
water temp at 70 degrees
oil pressure at 5 bar
and then the headgaset let go.
uber amounts of smoke and a megga mess in the engine bay.
found a headgasket and bolts on the shelf at wag benets so striped her down
cleaned her up and put it back together, checked block and head every thing looked ok. so on it went
started it up and she fired strait away and idled ok
but ive got a very loud tapping from the top end.
could i have bent a valve through hydrolick lock?
why did the head gasket go?
i only have 2 possible reasons. head lift or **** gasket
what u rekon

u might have bent a pushrod or theres a damaged piston u missed..do compression test
well problem solved,
it skiped a tooth and the exhaust valves were hiting the pistons.

Hi Dave
From experience those engines don't tolerate a lot of timing at WOT. Did your mapper listen for det ? If you can somehow send me your ignition map I'll compare it with some of the B18FT ones I've done.
wouldn't have happened with a c1j :coffee:
headgasket would have gone long before that. ;)

i cant extract the map from my ecu on my laptop fella as its not got a serial port.
altho i could do it on the pc at home i guess. as i have the cable
there were no sign's of det to the pistons or the head..
just spoke to maper on the fone he said theres not alot of ignition in it but i dont understand it any way lol
ill see what i can do and send it over

5500 in 5th is well over 70mph... may be your answer there! :laugh:

Ouch! :D
Might keep in mind for future though but i am tempted to go slightly bigger capacity after a while if i find i need to.
same crown design
just a difference in the skirts i beleive
