1G Car will not start...

[WKSDSM]

I just bought this car from a guy and I was told that the car would not start. The story was that he blew an oil hose while driving. The guy said the timing belt broke and caused this. I the first person look at it and said he did a compression test and got 0 on all four. he told me to just sell it . He later talked about buying it . so i took it elsewhere. I took the car home and went to work. I was up till 5 am looking for reasons. First let me say that the car would turn over but it just was not firing (It that makes sense) I had a few people who build drag cars down here in Florida tell me that I had one of two problems. 1 the car was out of timing or 2 the valves were bent. I take it to the drag car guy who said he would machine the head and replace the valves. The next day the guy calls me back and asked me if I was crazy. Every thing in the head was new. He tells me that the problem can not be what I was told and wants me to see the motor. Long story short. …… he checks the car out and calls saying the every thing looks good.. I saw no scaring on the pistons or anything. I don’t understand what could be the issue. I guess this comes with jumping into a car and not knowing what the history was. By the way the turbo was also new. Any ideas why this car will not start. The guy is only charging me 35 an hour so I’m not goanna be hurt to bad , I would just like to get this car running and get it out of his way . Please help...... thanks

If you get 0psi on all four cylinders, there's a major problem. Did the "drag car guy" pull the head and check that the valves weren't bent? A broken timing belt inevitably leads to the piston crowns smacking some of the valves. The valves bend, and you often get gouges in the piston crowns that aren't preferred (they lead to hot spots which lead to knock). And if he lost oil pressure (I don't think there are oil "hoses" on our cars...oil lines yes, hoses no), he could have damaged any number of internals, warped the head, etc.

I don't know what to say, but 0psi compression means bent valves, hole-in-piston, no rings, blown head gasket, and/or cracked block. I'd bet on bent valves if the timing belt snapped though.

Are you sure the valves are not bent? That's what first came to mind but if everything is new, then I don't really know what to say..

I would check the piston rings if you haven't already, that's another option that came to my mind.

If the heads for some miraculous reason fine then I'd check consider the rings. Also make sure the timing belt is on correctly. Make sure all the marks line up. Maybe the cams are off 180 degrees?

thank you ... 180 out .... i ve been doing so much research on this lately and thats kinda the only thing that make scene to me . Its funny you look for big things and over look small ones. ( KISS ---KEEP IT SIMPLE STUPID) I just hate that i had the head pulled. the head goes back on today and i ll know if this was the problem. Thanks for the advice everyone > If you have any other ideas let me know
