The block:
The 95mm pistons with two valve cut outs not four:
Engine Number:
Rtec stg2 heads.
The engine is,
71.12mm stroke,x 95mm bore .= 4032.91cc (246.1 ci) or 4.1????
Right now the history,
Phil (neils friend) bought this engine for his car,
BUT they had over heating issues from day one of the install, as it would dump the water out at any opertunity,
the car went well though even with this problem,
they changed the carb and inlet manifold thinking this was the prob and fitted efi, which seemed to agravate the problem further.
All 8 pistons are black not steam cleaned as if it was pressurising the bore,
could one of the heads be susspect???
Also can we make up some sort of set up to pressure the water ways to see if there is a leak on a liner or on the block and heads???
we were going to blank off the water way on the block face with a plate and gasket with a pressure gauge fitted, and fit a plate the other end of the face to block it off and then fit another plate with a valve for the air line at the block front (water pump inlet),
if this is ok what pressure do we have to test it too and over how long to see if a drop??
we will do a similar thing with the heads then,
the other block to the left of the rovertec one is another 3.9 which if the RT engine is buggered will use this as a base to rebuild the RT engine into,
I hope to have both engines here in the week when i will strip th RT one down to a bare block and test if we can or send away to be tested.
