Narrowed down my knock today

Well gang, today I finally got a full day to just work on my 'ROC and I found out what my knock was.

If I pull the #4 cylinder plug wire and rev the engine, it revs, no knock.

If I put it back on and rev it past 1500RPMS or so, knock knock knock.

So anyways I spoke to my engine guru and he stated that I probably have a piston which is rocking in the bore opposed to a rod bearing out because my oil still looks good, still gets good oil psi.

Needless to say, my 'ROC is flying with no motor / trans as we speak.

Well, at least you found out what was wrong. How long do you think it will be until you get that thing running again?

Well, I'll have the block back by next week supposedly all built up and I guess the time down depends on whether or not I want to do that T56 swap while everything's out

Yeah that's exacta-tic-ly what I was thinking.

Plus I have an extra T5 + shifter & shift plate that I am selling, and I already have a buyer for my complete T5 that's in the car now, so that practically pays for my T56

Will do man, I appreciate the support everyone on here has given me

The only problems I really see are the fact that I want to keep my stock speedo. How accurate is that Cable X thing? Is there any other way to go around that or did you install the Autometer Electric gauges?

well i currently dont have a speedometer

but i talked with david and he said its dead on accurate so ill get one eventually but its been so long i know my speed by rpms and gear.


essential tools for a 6 speed conversion

tinner snips, dremmel, lots of cut off disc's and bits and enlarging holes, impact gun for flexplate removal, clutch alignment tool, and tranny jack

I can do without a lot of gauges in my car evidently as my speedo gear broke on my T5 and I was doing the exact same thing, just going by my tach.

Plus my gas gauge has never worked. But I'll save that for when I get a new sending unit and 255lph pump and my rear springs so I can do it all in 1 shot.

My speedo is also not accurate right now, I also go by my tach. My speedo issue is not only the cable is bad but my speedo gear is the wrong one. I have heard they are accurate when they are working right and in good shape. Would rather have the Autometer electric ones but they are a lot of $. Nice pics, looks like things are coming along. Good idea on doing the sending unit, fuel pump, etc. all at once. I am putting in a new gas tank and fuel pump, etc. all at once some time this summer.

Thanks Will !!!

It's sitting for a bit because a fellow thirdgenner in need is borrowing my engine crane.

I need to get 30# injectors and a T56 trans still so... I'm not really in a big rush.

I have until July 16th anyways
