Figured this belongs in advanced tech since most general techies have not run into the following issue.
Purchased (many months ago) Wiseco pistons to install in a junkyard 6 bolt engine. Got the 7.8:1 pistons.
Cleaned up the block per usual. Had block match bored & honed to each piston. Reinstalled oil squirters and crank.
Tried installing the pistons but noticed the oil squirter makes contact with the bottom of the piston!
Fairly sure the piston is installed correctly because i used the stock pistons to go off. When stock pistons are held with the arrow pointing towards the front/timing belt end of the engine the larger valve cutouts (intake valves) are at the left side (towards the rear of the vehicle if the engine were installed in the car). Installed the Wiseco piston in the same manner and piston hits the squirter and does not allow the crank to rotate.
Questions:
Did I install the piston correctly? Install the oil squirter correctly (don’t think its possible to screw that one up) or are they specific to each hole?
Has anone else who used Wiseco pistons experienced this problem and if so what did you do about it?
Are these pistons designed to be run without the squirters? or are the exhaust valve pockets bigger than the intake pockets for some reason. I assumed the new pistons would be like the stock ones which have the intake pockets larger than the exhaust pockets.
Guess i'll call the shop i bought them from tomorrow but wanted some input first from the (advanced) dsm crowd first.
Thanks in advance for any help.
