Valve cover stripped

[Kartiac Arrest]

If the bottom bolt strips on the valve cover can that be fixed? Or does the cylinder need replaced?

Consider a longer bolt? One from the side cover would be a good reference.

The bottom bolt is threaded into the block. If a longer bolt does not fix the issue, the you can legally use a thread repair per Briggs rules. If it was any of the other 3 valve cover bolt holes, you would need to replace the rocker plate. Either way the head does not need to be replaced. Also, don't over torque those bolts. 125 inch pounds is plenty and will not destroy the threads.

i have not seen this valve cover bolt that bolts to the block.

The valve cover bolts are 6 mm the side cover bolts are 7 mm.
The ones in the blower housing are 6 mm.

The bottom bolt in the valve cover threads into the head not the plate.

So I put a side cover bolt (7mm) in there now. Running the Cup Kart Grand Nationals. Will that be considered stock?
