How many of you racers out there actually pull the pan and loosen the rod bolts during the off season? I'm asking this question based on the BME maintenance procedure. Needing some input. thx matt

I've known people who didn't and then wished they did when the rods exited the block later on. As far as I'm concerned, I don't want to use any self cracking connecting rods in anything I build. I'll stick to GRP rods, no BME for me, thank you.

I talked to Bill Miller himself about this issue. He told me what can happen is a type of corrosion that can cause a crack parallel to the bolt hole. I was told that there will be no partial or beginning crack. Either it will be cracked or nothing at all. That being said my short block sat for several years before I used it. I had no issues. This winter I'm going to check my rod bearings anyway. I'll just leave everything loose until spring. Doug

I would think if it was corrosion causing the problem, you wouldn't want the bolts or the bearings in the rod at all.

That info was relayed to me from Mr. Miller himself. Doug

I wasn't disagreeing just commenting. I think the reaction between dissimilar metals is called galvanic corrosion or something like that so steel rod bolts and bearing shells I suppose technically could cause a problem when in close contact with aluminum.
The type of corrosion he mentioned had something to do with oil and the bolt material, not dissimiler metals. Doug

I guess I've heard it all now. Back your rod bolts off during the off season. Yea right. What if you are somewhere they race year round? Are you supposed to back them off during the week?

We often go 2-3 months between races and have never backed anything off. We use Bill Miller rods because we think they work the best. I've seen and heard of others fail. The trick with aluminum rods is to count your runs and when they get to where you feel they should be changed then change them.

Wasn't it Bill Jenkins that said "We take them out of the motor every 60 runs even if they look good. Before you throw them away, hit them with a big hammer so you won't be tempted to take them out of the trash."

back the the metal was a much poorer quality and design improvments add to a longer life
I work with dozens of metals each week and I cant agree with this statement. But design improvements yes.
