96 3100 Rods

[94GPGTP]

is there any engine out there that share the same rods with the 3100?? i just need one rod.. I do have a 3.4 TDC block and was wondering if those rods were the same.. i doubt it but just curious...

heres my cam ForcedFirebird, and my bent connecting rod..

[ForcedFirebird]

OWCH!

How'd that happen?

I have 5 extra rods from another engine, but need to press the piston off before I can let it go. ARI sells rods for about $20, though.

Does anybody know off hand if the timing lobe on the cam is the same on a 3500 as a 3100? I'll print the pic and check out the 3500 cam tomorrow or Thursday if no one knows.

you know the engine ran fine before i tore it down.. not one funny or odd noise.. it had oil all over from cheap leaky gaskets so i tore it down to change gaskets.. well decided to check the rings and pistons, timing chain and sprokets, and decided to pull the cam for the hell of it.. well just today i found the bent rod and pull the pistons out last friday..

the cam has grooves in it and the cam bearings are bad.. i have a 3.4 DOHC block and hopefully those rods are good if not u will be hearing from me..lol

Just let me know about the cam.. im looking around for one and trying to get it on the fast side.. im trying to get this motor together so i can get on the road..

thanks for the help

The cam is the only thing left in the block, lol. That 3500 got a working over I tell 'ya.

It has 20 something thousand miles on it. The main and rod bearings looked brand new.

Here's a pic of the cam and timing lobe. It looks like the 3500's have a 50% lobe and yours is just has a notch. The 3.4 SFI's have justa a tab on them. Wonder why the changes from GM?

This has been discussed many times. The pickup is different, by the sensor still picks up the leading edge, which is in the axact same location between all 3 designs.

so i guess they are different... what do i do now??? its knida hard to find a cam... do they make oversize cam bearings?? i havent found any at the local parts store.. maybe someone out there knows if they do ir not..

So it will work, right Brad?

[bszopi]

Yes. Worse case would be to replace the sensor with one that matches the trigger...

yes sounds fair.. the only thing i ask... look in the picture of the 3 cams next to each other... i think its the angle of the camera but the way the cams look it lokks as if going to the right the cams get smaller?? i need a second opnion.. also the cam is in good condiotn.. able to run it?? pm me where i can send paypal payment

[bszopi]

Its the angle of the camera. They are all the same size.

[94GPGTP]

ok cool. just making sure..

ForcedFirebird PM me.. thanks

[ForcedFirebird]

Yes it's in good shape. I bought two 3500's about the same time and I can't remember which had what, but one was 22k miles and the other had 32k. Both were from '04 Malibu's.

I'll send a PM.
