I have a uim leak and was going to replace it. I did some reseach and found that I should go ahead and replace the lim gasket with the alum. frame since Im already there. Next I read that porting the lim gives you a lot better performance. My question is, is there anyone out there who has a L36 plim they dont need or that can help me port mine?

I have ported out a couple in the midst of changing out the gaskets. Depending on how much or perfect you want it will depend on how much time it takes.

I've used an air die grinder with a pretty aggressive cutting bit that a machinist buddy gave me and it took me about 20 minutes to open up the ports. While I didn't polish everything there was a good amount of blocked port that was opened up.

The closest that I would have would be a dremel tool, Would that work or would it take forever?

I've used dremels before as well. Probably suggest the aggressive sanding drums if we are heading that way.

How would you go about opening the ports? Would you lay the gasket on the intake trace the ports out with a marker and start grinding the openings to match?

Just found a thead that explains everything. Thanks for your help Bill.

Where did you find the thread?

Go to search and type in porting Lim. Theres a lot of good info in the theads.
