22R Problems

I'm helping a friend get his 86 Toy P/U running again. Engine will crank but will not catch. We've checked the compression to find 0 on all the cylinders. The engine has never overheated and it was working fine until a week ago.

I'm thinking it's the head gasket, but if the engine has to be rebuilt, it's better to buy a rebuilt engine. For some reason, 22R engines are more expensive compared to other newer engines.

Anyone know where we can purchase a 22R for a decent price in Southern California?

TIA

Zero? 0 psi? As in nothing? Nil? Even a piston with no rings will register some psi.

The timing chain is intact. The cam does move and the valves actuate. I have to leave town on business, but I'm going to pull the head off when I get back this weekend. I'm suspecting it's a blown head gasket, but all 4 cylinders blown? Someone suggested the seat rings fell out. I won't know until I get the head off. My friend does not have a lot of money to spend, so I'm trying to avoid purchasing a rebuilt engine.

Thanks again,

JW

I'm thinking that has to be some sort of misunderstanding. Either that, or a broken compression gauge. Not seated firmly? Something.

I would sure try more troubleshooting before I sprang for a rebuilt engine. Spark? Fuel line? Fuel filter? Gasoline in the tank? Don't laugh about that last one. It's happened before.

LOL, There is gas in the tank. Spark from the plugs.

If the timing chain is intact look at the gears very closely. It sounds like it is radically out of time. Possibly the chain jumped, but when that happens it's usually only off by one tooth, which makes it run rough, but it runs. If you can determine when #1 cylinder is at TDC on the compression stroke, look at the valves. If they're both closed, turn it over backwards and see if one of the valves starts opening fairly quickly. They should both be closed shortly after the piston is at bottom dead center. The fact that all cylinders are at zero indicates a mechanical problem, not a blown head gasket. A blown head gasket takes out 1 and often 2 (adjacent) cylinders. But not all 4 at the same time. That would be very rare. Good luck with it.

It would seem odd that it ran fine and overnight no compression. Even with a blown head gasket some compression should be shown. The gasket doesn't totally disintegrate with no indications. How about head bolts? Even if they need to be re torqued some compression should be indicated. All valve seats can't go all at the same time. The truck would indicate some sort of trouble before giving up.
