Science of speed sells them and can do the bore/hone and install.

 

While I've got the head off, I'm going to pickup some ARP's I think.

They also sell Rod bolts, what do you all think about those?

Re-use the stockers, or get some ARP's.

Don't say get ARP's if you have no experience either, lol.

 

Come on, it's obvious.

See the groove the top ring sits in? Notice it is wider on the left than on the right? That's because the land the ring sits on has collapsed.

 

stock rod bolts are fine if the motor has never been apart before, and only torqued once. the service manual calls for the torque number plus 90 deg. thing, so i wouldn't feel comfortable torquing the rod bolts too many times.

I used ARP's in my motor with an OEM HG just because they were in stock at xenocron and he always gives me great prices.


honestly the bores do not look bad at all. would i use them like that? hell no. but they do not look like they took too much abuse for all the comp numbers being that low.

and the second piston pic, that relief is deff. melted. same thing happened to my motor, but on every single piston lol (too much timing)

 

Pardon my ignorance, but is that much carbon on the skirt normal for that power level, of is it from the ring failing? Just wondering.

 

I dont think there is enough room to bore it .250". Do you mean .025"?

 

jesus, I have no idea what you guys are talking about, lol Im envious of your knowledge

 

.25mm.

 

Thats even better. Thats only about .010".

 

The timing was conservative, so it wasn't a tuning issue. On the last run, we forgot to turn the fans on, so basically the i/c wasn't doing it's job, all that heat was going into the motor and it was to much for the methanol to remove, simple enough.

Being on the threshold already, pushed it over the edge.

Simple mistake, cost me the motor. I figure it was bound to happen sooner or later, when you push it like I did...stuff happens.

Learn from your mistakes, and do it better next time.
