Done with the block.. just need to swap the newer parts over to it from the block thats in the Jeep that exploded. Now that ive started to tear apart the Jeep to get the old block out.. it really doesnt seem that hard to pull the engines in these things....

Another question... is it bad to drain the Torque Converter?? I was reading my FSM, and it says to make sure you keep the Converter in the housing. I just kinda assumed since i was in there it would be a good time to go ahead and drain everything out of there kinda like a real flush...

Just fill it back up as much as possible before you put it back on.

Probably stupid questions but....


Since i replaced rings, and lifters i'm going to need to break in the rings correct?? Is this procedure the same as breaking in a Cam? Should i consider using some type of break in additive?

Thanks!

The cam break in is 2000-2500 varying rpm for 20-30 minutes. For the cam break in you want a good break in oil. Non synthetic. I used Brad Penn 30wt breakin oil with no additive. If you get something off the shelf you should add a ZDDP additive to it. However, I don't know of any off the shelf oils that would be good for breakin anymore. Maybe diesel oil, but you need to make sure it is CI-4, not CJ-4. And make sure it doesn't say anything about low emissions or other bio-friendly junk.

The piston ring break in is different. See Hasting's recommendations: http://www.hastingsmfg.com/ServiceTips/ ... cedure.htm

Does cam break in apply when replacing lifters? Or only when replacing both?

When replacing either. You can put new lifters on a used cam, but never a new cam on used lifters.

Im going through and removing old parts from the engine i threw a rod in. At least the ones im going to use on the used engine. I was going to use the two year old timing set, but thats out of the question now.. its not broke, but the dowel thingy that protrudes out the cam that goes into the cam sproket was broken. It must have been put under alot of stress... so i dont want to chance a stretched chain.. Plus it enlongated the hole in the cam sproket for that dowel pin...

Anyway, check out this harmonic balancer:

Think its still good to use? I dont know how it got beat up on the end like that... seems kinda weird.

From the picture it looks like end of the balancer is just damaged. If that is the case, that is fine to use. Looks like someone tried to install it by pounding it on.. i bet the thrust bearing loved that.

Probably another nooby question but;

I installed the timing set last night. Got number 1 at TDC, and then lined up the dots on the gears. After i installed the cover and balancer, i had to crank the engine 180 degrees to get the notch on the balancer to line up at 0 on the timing cover. This tells me when i installed the timing set, the engine was at TDC on the Exhaust stroke right? If thats true, am i going to run into any issues, or should i remove the timing set again and install with the dots lined up now that im at TDC on the compression stroke...

Thanks again for your time.

That is how it is. For some reason they use TDC on the exhaust to line the points up.

Sooo... more problems of course.

I was getting everything buttoned up on this new to me block and i was going to put the RENIX CTS on it, but the port was blocked with a plug. I tried to get it out of the block, but the plug was like heat welded in there. I tried everything and i just couldnt get it out.

Does anyone know what thread size / pitch it is so that i can get the correct tap? Ive already drilled it out.. i just need to tap it now. What a pain in the ass!!

Its wasn't plugged, just never drilled. It should be 1/8-27 NPT, but I am not sure. I suggest bring the sensor with you when you get the tap.

Your thinking of the sending unit at the back of the head I think.....

I'm talking about the CTS for the ecu. Its usually right below the second freeze plug from the front.
