I don't want it to go, because i know if it does i will have to get a new engine or P/S and rod.

Yea, it's funny i know. My engine runs great and everybody on here knows what hell i put my poor little vspec through
There is only 1 rod in your engine Dreaux..Thats the connecting rod, also referred to as the Con Rod..Always a good idea to replace it after the first couple of gallons, but I would recommend you send it out..These little engines are very easy to scratch the sleeve or bend the piston skirt..then your in a world of shit..

PS the other thing in your engine is called the Crankshaft

Is thier a way you can inspect your con rod to know if it is overstressed?? THis is how my other engine blew. The rod snapped in half and now it needs a new piston and sleeve

You can tell from the play/tolerance in the crankpin where your rod sits on it..I highly doubt you will be able to tell if it needs replacement, but if you want to give it a shot..You will check to make sure it sits snug on the pin. factory tolorences are slightly snug, and if you can move it up or down, or side to side, that means that the pin hole is stretched or worn. You also need to do the same thing at the other side of the rod where it connects to the wrist pin (piston)You also need to check that the rod has not been stretched which means you need to measure it, but since you haven't measured it when it was new, you will not know what it should be...Send it out Dreaux!!

I've had three Vspecs and never had a rod failure on any of them.Got around 7 gallons from the piston and sleeve.Had one pinched. It's rod showed wear but didn't fail.Never have stripped a head bolt.Are you using some type of threadlock or something?

and pete, tools are fine,its the bolts. when it was new i used proline tools, got 2 out and 2 stripped. when i rebuilt it i put new bolts in. my dad put new bearings in his vspec. different tools same result. now with the new bolts in mine i used a set of craftsman, same thing but all 4 now...... my proline tools dont strip screws so i know there not bad.
1: there is no reason the head screws should strip. After removing hundreds of head screws(os being a big part) I have never stripped one... ever! Either your tools are complete junk or you are doing something wrong.

2: When you replace the bearings again, go with TKO's again. The Speed bearings are better than most, but still not as good as TKO.

3: you will need to get the head off to check shimming.
