The aluminum sounding tick in the background is normal, but that louder noise I would say no isn't normal.

i dont really see how floating wrist pins will cause a noise that sounds like piston slap. There isnt really and side load on them that would make them move back and forth with any force so i dont know how they would make noise. My motor and chris' both have floating pins and dont make any noises that sound like piston slap.

My 75.5 vitara sounds stock. I'm pretty sure the people saying it's the wrist pins are just trying to reassure themselves that improper clearances couldn't possibly contribute to pistons slap.

The solution to piston slap is running 30 psi.

I don't think what Tom (the old dude I was talking about) meant that the pins were moving side to side, but that there was clearance between the pin and the rod and clearance between the pin and piston which is causing some noise. I'd like to see more research done on that.

that chic in your avitar is hella sexy

sorry i cant see sigs on my phone, just the name and there post. no time/date, no post count, no pictures. pretty basic. but i get it, he isnt a newbs and just needs some help. didnt flame him but i didnt try to get some better info out of him.

Re: no longer smooth engine
 

from reading everyone elses posts, i would say its not something to be really worried about, but worth keeping an eye on. i guess with vitaras you just have to have a little bit of experience to get the right p2w clearance. someone should make a reliable chart an post it in a sticky. pretty useful info.

Re: no longer smooth engine
 

FJT said once said that he recommends a p2w clearence of .001 for every 100 hp your shooting for. so if its 400 your after then go with .004. not sure if that is correct info just posting up what he had said before.

if thats the case, then imho youve got a big problem
