New to the forums here but big fan of ETCG. I really need help with my situation so any advice will be much appreciated! ill try to keep it short. Basically I sold my car (01 neon) for a 2000 celica gt that I was told just needed a radiator and bumper (was in minor accident). Of course after I bought it the car wouldn’t start. Sat for two months, cranks well so we did the diagnostic. Car got fuel and spark so I was scared right then and there. Bought a compression tester and vehicle had zero compression in all cylinders. Just brought it to a shop they tore off the head and told me my camshaft is broken followed by my exhaust valves and I need a new engine. Of course I’m an idiot for not getting my money back but I really want to fix it. My question here is do I really have to replace the whole engine or would I just be safe replacing the head? That would save my life if I could just throw on a new head and have it run fine but the mechanic suggests to just get a whole new engine. I really need help with this. Thanks!

the head would be the cheapest way. you also need a cam. before you purchase any parts you will need to asses the damage that was done.
you will need a complete inspection. if the engine can be saved you will need to do a cost and labor tally.will it be cheaper to replace the engine
or refurbish the engine. good luck and keep us postedTo determine the condition of the internals of the bottom end ( main and rod bearings , piston rings , cylinder wear , etc ) you would need to disassemble the motor and mic everything. that said- you could put a rebuilt head on it and get it running and then do a compression test , leak down test and oil pressure test in order to determine what condition the bottom end is in. once the head is on and everything is buttoned up you can do the leak down test without the car being started. compression test and oil pressure test will need the car to at least turn over. my concern would be that the car was run hot to a point of head failure and you may have cylinder damage-ie: cracked block ( you can – with the head off- rotate the engine with a breaker bar and check the walls of each cylinder as the piston travels down ) Have you drained the oil and checked for any metal bits in it ? if you do just the head you may want to find a decent ” used ” head and put that on ( being that the bottom end has over 140,000 on it. ) that way if you find out the the bottom end is trashed you will not be out near as much as installing a newly rebuilt head.

I’d also be weary of warped cylinder heads as well as more internal damage if it is an interference engine.
Still, a broken camshaft? S:-o
I would probably find a used salvage yard motor. It may be cheaper in the long run.
Keep us posted.
Welcome to the forums !
How many miles on the current motor ? ( what size motor- am assuming it is a 4 cyl ) in your post you also stated needing a radiator so I will guess an overheat situation probably occured as well as the cam shaft failure. if the over all condition of this car is good outside of the current motor failure I would recommend putting in a low milage used engine Check out this website : risingsunengines.com. keep us updated.
Hey thanks for the reply! Got a quote from the website so thanks for that. The car has 142k so same with the engine. It does however have a brand new transmission and clutch installed by Toyota. The engine is a 1zz 1.8L 4CYL. I assume what happened since the guy is an idiot after the accident he still drove it and with the radiator being caved in and no coolant the head went. Ive already picked up the bumper and radiator etc. Why would you recommend replacing the whole engine and not just the head? Just curious because money is an issue ( still in high school). If I were to do a whole engine swap I might as well go with the celica gts engine. Its pretty much a direct swap and you get a lot more power out of it but I just want was quickest and cheapest.
Im not sure if it helps or not but I forgot to mention this car has a timing chain instead of a belt and it is one of the few cars out there with a non interference engine.
To be honest if you find a broken cam shaft in an engine it’s not likely the rest of the engine is in good shape therefore if you had come to me to fix it I would be recommending you replace the engine with a good used unit rather than trying to repair a potentially bad engine.
Thanks a lot for your advice! (everyone). Ill get someone to remove the head and look at the walls but I think I am just going to do the 2zz swap. Its going to suck because I need a car now but ill figure it out. I wish etcg was on the east coast! Thanks!
I agree with the 619DioFan above. If the engine was run hot over a period of time, there is probably damage BELOW the head as well.
Just replacing the head would be like putting lipstick on a pig.
Probably going to need an engine swap, which is not the end of the world. Of course, with your new radiator and cooling system, watch out for future over heats. You do not want this to happen again.
when i lived in los angeles i would buy used japanese engines for $199 complete,,look around….screw the old engine…
I think it’s just a rebranded Lisle Tool product – you can save yourself about 1/2 if you look around:

Do you guys think you would have access to use it? Looks good for removing the sensor once the downpipe is off the car, but that’s usually not how it’s done.
