Y'know, I made a comment in another post that I was getting a very wretched knocking noise.

I ordered the balancer, but cancelled it when the motor locked, as it will not do any good on a motor that ain't running. Just for craps and laughs, here is the video clip of it running...there isn't any picture but you won't need it....

drop your oil pan its really easy that will tell you alot more than trying to tunr the balnacer

take off the inspection cover on the flywheel its the black plastic thing get a prybar or a big flat head screw driver and rotate the engine backwards can you do this?

I did this when I took the starter out, and it didn't even flinch

Ok, so assuming that this is a spun bearing, is it feasible to repair this in the car or just trash the block?

If you're going to do a rebuild (which you'll have to, or get a new short block) take the engine out. It'* always easier to inspect for damage when the engine is on the stand. The spun road bearing may not be your only problem.

I can't imagine dropping the crank, etc., while the engine is in the car. Sounds like a recipe for disaster to me.

the best idea yet is get a junkyard motor and change the intake gaskets before you install it

...my thoughts are all blank right now. Since I live in an apartment complex, my working room is next to nil, as my landlord doesn't like inop cars in the lot. My buddy is hellbent on getting the motor out in the lot, but he'* a few quarts shy of a gallon. Do I want to keep the car? Absolutely...I knew an engine swap would be in its future, just not the immediate future. So my options at this time are pretty short...aside from putting it in storage and parting the motor out there.

I would most definately do the short block option, but there is a small problem with that: the junkyard here NEVER stocks L67'*. So unless I can use a Series 1 n/a short block in this rebuild, my new acquisition is gonna sit until I can get a break, both timewise and financially.

Would an L27 short block work? Probably. Almost certainly. Is it the same? No. There are a few differences for strength and durability.

Thanks for the insight...so at this point I have these options open to me:

1) Rebuild what I have. Mainly just the short block...heads seem to be in good shape, and I can do the rebuild on those myself if I needed to. Same with the */C. But the block is going to have to be pro-built out in town, or if there are a few members who would donate their garage space...... :?:

2) Part it out...simplest, probably will get most if not all my money back, and I already have a few members sending me requests "just in case".

3) Swap. Would be easier to locate a Series II than a I, but would the stock trans mate up to it? And could a Series II motor be controled by a Series I ECM, with the chip custom burned for it, or maybe I could go with the Megasquirt system.

Well, since my other thread was locked, I guess this one is gonna keep going....I had intended on closing this thread since the original problem had been solved.

Frequently I loan out garage space to club members.

Got another motor job on it'* way very soon.

Bad news is you are about 24 hours away from that open garage space.
