Case in point, we recently installed a fully built bottom end in a customers car (I should point out it had no thrust problems prior) the crankshaft endplay had started to change within 1000kms. It was greater by .002″. That didn’t have us worried yet. Had the customer not cared to come in on time for his first scheduled oil change it may not have been detected in time. We really couldn’t believe it could have been a thrust bearing failure so soon, considering, my machinist (in my books one of the best) who takes great care in assembly had checked the crank after it was ground, and then checked it again after he had assembled the short block. Being a stickler, and I hate leaving things to chance knowing the finicky nature of the 2g, I also checked the endplay. It was within spec. The crankshaft endplay had been checked on three separate occasions, yet the thrust bearing still failed. Why? The car had not been abused, the owner was very careful with the car obeying the break in rules. He had even requested I go with him the first time he put the car thru it paces, after the break in. At 1500km’s we went for that pass. Something didn’t sound right, we came back to the shop and heard what sounded like the early signs of crankwalk, the trigger plate hitting the cranksensor.

Measuring endplay with a dial indicator, we were now out of spec. We were screwed. Who is at fault for all this and who is gonna pay for it? I can personally tell you from experience that I do not like to do things twice, especially an expensive shortblock like this. All I can do is pray for no damage and swallow it hard. Up to now I had been lucky, almost all of the 2g rebuilds that we had done had turned up shiny. So I did some research, I came up with no answers. Basically people told me to keep doing what I was doing and pray they hold together. Forget it, I needed more definite answers than that. Everyone I spoke to in the last 2 weeks, I had quizzed them on the topic, be it parts counter guy, old school domestic car racer, engineers, whatever. Everyone had either no answer or a theory. I had my own. But still no answers.

Something Jeff Hill at Turbotrix told me, was he had heard about a misdrilled oil passage. Danny, my machinist mentioned something about core shifting of castings happening on old chev smallblocks possibly obstructing flow. My good friends Jimmy + Ryan at J+R Trading and I spoke about it over the phone in great detail, we mentioned “block seasoning”; a process some european manufacturers partake in. They cast a block, then leave it outside well oiled to “season” making sure there is no nasty core shift. Nowadays they are “pasteurizing” them or “pickling” them to speed up the process, whatever you wanna call it, manufacturers everywhere are taking shortcuts to keep the cost of automobiles down and their profits up. Besides, who has time to keep oiling a block in the backyard for a few years, by that time most engines are out of production.

Here’s a comparison pic after the carnage, the cut on the 2g block was not exactly thru the center of the gallery, measurement with a bore gauge showed that they were in fact the same diameter, But you can just barely make out the notch in the 95 main journal (arrow) where our little friend the hidden 2g oil squirter popped out of when we were cutting.

This is the 95 block cut about 6″ down. You are looking at the block the way it sits in the car, except the top 6 inches have been removed.In the foreground (A) you can see where the oil squirters reside. They are pressed into this hole. They share their oil supply with that supplied to the main bearings.In the background (B), you can see the size of the main oil gallery. It has plenty of volume, but once again more than the 93 (hmm… this gives credence to the clutch switch theory. The larger volume to fill will take longer on start-up to build pressure in the system. Possible but pretty far fetched)At the bottom right hand corner of the picture, you see the main oil gallery and a main bearing journal gallery (small black hole). Oil flows from the pump to the main oil gallery, then through the main bearing journal gallery, into the journals, then feeds the main bearings, and crankshaft then connecting rods.

So here It was, the oil jet. didn’t look like a restrictor, such as is featured on the 1g block, but looking down one end it looked like a check valve, blowing air through it proved it was. Taking it apart answered a few questions.

The check valve squirter was probably a good idea in some office at Mitsubishi HQ, but it didn’t look so hot at J+R HQ. With the squirter relocated to the mains you would not want to be squirting constantly at lower oil pressures, like when the car is at idle. Nor would the bottom of the piston need cooling at idle. But in the same regard the fact that it is so small, it could easily fall victim to contamination and allow the ball not to seat properly. When disassembling engines it is commonplace to find some scratches right at the orifice of the oil feed on the bearing surface, this comes from particles that the oil filter has not caught. Remember if an oil filter gets clogged, some have bypass valves which allow the engine to continue to get oil. You get unfiltered oil, but you still have a motor.

In the meantime, over here at Magnus we will no longer be assembling 2g blocks with these oil squirters in place. Like the balance shafts we find them too risky, any time we can eliminate a source of failure on a motor, we’ll do it. I’m not asking anyone to pull their motor right now to do this, but any new block t
