Crankwalk?

I just drove my Galant 1000 miles last weekend, and was super stoked that I didn't burn a drop of oil (new pistons). Then yesterday I started noticing an RPM drop whenever I push the clutch. By the end of the day the RPM drop was joined by an illuminated oil light. On my way home, the engine began to stall whenever I push the clutch to come to a stop. Starting to hate this damn car.

Thoughts or insight?

Does it have oil?

Still full of oil. I just put a pry bar against the harmonic balancer, and I want to barf, or take up hard drugs.

So last Sunday I crashed my downhill bike really hard. I think I separated one of my ribs from my sternum, and now I have 1/8" of friggin' crankwalk. When I sneeze it feels like I'm taking a baseball bat to the chest.

Ps. I was joking about the heroin. I wouldn't even know where to get it.

You can get better drugs from a Doc if your in pain like that.


Sounds like your thrust washer took a shit. Do you have the clutch switch disabled, I.E., able to start the car in neutral without pushing the clutch pedal in?
I bet the bearing was dry at some point while cranking with a heavy clutch.

Was the crank machined at all?

I have been taking 800mg of Ibuprofen every eight hours since the crash up until last night because my stomach wasn't feeling right. I didn't disable the clutch switch, but that's about the first thing on my list now. I thought about it, but figured "eh what are the chances I'll get crankwalk on a six bolt". The bearings are standard size Clevite/Perfect Circle, and the crank has never been machined.

I want to toss another set of bearings in there (assuming the crank isn't scorched) but I worry the same thing may happen in another two thousand miles. The crank I used for the rebuild actually came from a N/A block I had laying around. It just seemed a little smoother than the one that came out of the engine.

I just noticed the mains are still in that N/A block I took parts from. Maybe I can just pull the pan and slip them in without pulling the crank, and cross my fingers.

Don't swap main caps. You can't do that. Also did you measure the crank before using it?

You can try new bearings, but Clevete is ok, but ACL race bearings are far better.

Yes, you can swap in bearings without pulling the crank, you gotta be careful and through, also what did you use for torque on the cap bolts?

Oh, and in honesty, I'd pull the oil pump off and clean it out and check the oil passages and make damn sure something didn't block up a hole somewhere.

Post up pics of bearings for us to look at.

I wont swap main caps, I know I can't do that. I was referring to the used bearings. It's going to be days before I see a new set of main bearings for this thing. Stores don't even stock wheel bearings for this car.

I'm working my way around the oil pan with a putty knife now. Pics to arrive shortly.

I can feel grooves in the thrust surface of the crank on one side. I can barely believe this carp.

That crank looks mighty old there buddy, you ensure it was safe to still use before the new bearings?

How did you set the thrust bearing when assembling?

That looks like a dry bearing to me, or contamination of the bearing surfaces.

The oiling channels in the crank should be cleaned out very well, in fact BogusSVO did a write up on it and how he removes the balls in the counter weights to clean the crank out.

I blasted out all the crank passages with brake clean, but I didn't remove the balls. That particular bearing is lubricated directly from the block, and doesn't have any passages in the crank.

Setting the thrust or seating the thrust is a joke. Hammering or seating the crank is a waste of time. If your clearances are right you will not have issue. If your machining is on then things will go smooth. In almost twenty years I have never done it. And I have assembledover 125 4G63's. I tap the thrust into place, torque it all down and go about the rest of the assembly. Then again, we don't usually run virgin cranks. They are all taken to our crank guy and usually machined. I could not even remember the last time i used a stock untouched crank in an engine.

It was wrong before you ever started.



I GIVE ZERO FUCKS. I HATE YOU ALL.

^+1. If its getting new bearings, its getting polished/turned by my machinest. my stock crank still needed "correction" to receive a set of factory pistons.
Those were tri-metal bearings you installed, right? full oil groove center or just partial?

I haven't pulled the whole thing apart yet, but I did find flecks of crud in the main face of the bearing too. Only on the trailing edge of both bearings. The mains are a $29 set of Clevites, so probably not tri metal.
