If you have an oil pressure guage than that is the correct sending unit. The one for a low pressure light only on the dash is smaller.....find a way to close up that open sore on the block!

Hate to say it but I think that block is trashed...

I'm kinda surprised at the size of the pistons though. According to the numbers on the piston, they're Sealed Power brand, .040 over:eek:

Not that .040 seems like a huge number to me, just wasn't expecting that on a reman motor.

Jasper does a bit of everything so it looks like that person went for the optional over bore.

My dad did that when he got one installed in his old Ram.

How so? What are possible draw backs to that being there? I wasn't exactly nice to the car at first when I got it, I put it through it's paces when I got it, one to see how it ran, and two to see how the extra horses felt compared to my old Sport.

Me likey!

I'm not gonna thrash the hell out of the motor after it's done, and it's not getting sprayed or blown: so what are the negatives to leaving it alone, and what would be recomended to fix it?

Also, it's and old "wound", since there is no trace of the missing material. Do you think Jasper would have re-used the block if that was a serious issue?

I would think that if the hole is in a critical area then your crankcase won't be pressurized. That, and you'll get a hell of a lot of oil in the valley. I sense bad things about that...

I also don't know if it can be repaired. It's tempting to say "JB Weld". But that's a pretty big hole...what would you say, about the size of a dime, nickel, quarter?

So you're saying you ran the car with this hole and the engine performed alright? What weight oil were you using? You didn't hear any ticking in the valvetrain?

Hole size: since it's oval shaped, it's wider than a dime, but not as tall as a dime. It's between the lifter valley and timing chain area. Second pic shows the hole above the cam. If something made the hole by going through it, it looks like it would've gone from the timimg chain area into the lifter valley.

The car ran great when I got it, but I haven't had it on the road since last summer. I've had it running plenty of times moving it around though. Never heard any ticking, but then again the car had a MAC cat back on it, and that sort of thing would have been tough to hear.:D

Not sure what weight oil was run in it, never changed it, but when I drained the oil it looked like it wasn't any thicker than 10w40, but thats only a guess, since it didn't look very thick.

Don't worry about them... Oil drain back...

Would have been nice if they had been cleaned up a bit, but I guarantee they were there when Jasper rebuilt the engine(and you really think they would have sent a engine out that was going to have a problem when they had to warranty it??)... If you were going to totally dissemble it(and I wouldn't on a 14K engine, looks good to me), I'd deburr them but don't think I'd take the chance of getting cuttings in a motor I was getting ready to run...

.040 over is fine, one of my racin' buddys put over 1600 drag strip passes on a 308 till the crank broke(yeah it was ugly)... But not as ugly as the DSS 331 he replaced it with that broke a rod the sixth weekend at the track...

I'm not pullin the crank and pistons, just lettin those ride. After I clean up some of the rust on the block and add some paint to it, I'll be putting in a TF stage 1 cam and twisted wedge heads. I have some 1.6 alum. rockers to throw on as well.

While you have the engine apart, it wouldn't be a bad idea just to cylinder bores to make sure they are within spec. Also, you could take the main caps and rod caps off and inspect the bearings, just to make sure there is no excessive wear. It's easier to do that work now, then when its in the car.

Hey guys, I'm planning on using these intake gaskets: http://store.summitracing.com/partdetail.asp?part=MRG%2D5835&autoview=sku

With them having the built in silicon seals, would I still need to use something like Permatex High-tac on the water jackets still, or would that be over redundant?

Thanks for the help, all!:bowdown:

Um, anyone with input?

I'm planning on some assembly this weekend, so I need a little insight. Thanks, guys.:hick:
