1986 Honda Accord Manual

the car has a new distributor, coil, new wires everywhere between, new fuel pump, new water pump, new fuel filter, new thermostat, new plugs but it won't start. The car is fuel injected

everything works, it has spark, it has fuel when I open the bleeder vaulve but it wont start.

the car used to overheat so I think it might have a crackedhead gasket. Maybe I dont have compression?

Hi brand0nmustdie,

You still have not tested the compression?

No I have not tested it, someone just suggested that that might be the case.
I'm not sure how I could test it at home without taking it in somewhere to be tested.

Hi brand0nmustdie,

You need a compression tester to do it.

Prodecure for testing is simple. If you can get a tester, I can show you how.

They came out 80lbs on the first cylinder, 110 on the second, 100 on the third and 105 on the fourth.
Someone at autozone said they needed to be at least one hundred.

Hi brand0nmustdie,

I would say 125 psi is required and not more than 5 % difference.

Did you do a wet test? Ie, put some engine oil in the cyliinders and test pressure again?

86 models sometimes have proble with valves not closong fully due to carbon getting into the valve seats. Turn the pistons down and give the valves some taps to get the valves to close fully and try again, might help unless the head gasket is blown ( you could try retorquing the head ).

how do I turn the pistons down?
How do you retorque a head?
If my head gasket is blown, is it repairable? If so how?
I've bought a lot of new parts for this engine and I would prefer not to have to replace the engine.
Could you include some sort of visual aid if at all possible?
Thank you.

Hi brand0nmustdie,

Sorry, I got no visual aids.

Turn Engine to TDC and from there turn another 90 degrees, piston would be halfway down.

Retorque means retighten the head bolts.

If the head gasket is blown, you need to remove the cylinder head, reface it and reinstall. If you do that, I would suggest lapping the valves.

Hi brand0nmustdie,

At the rate we are going, your car would still be in the garage by Christmas.

I would suggest getting a repair manual to speed up things and get a better understanding of repairs.

TDC = Top Dead Centre, ie when the no 1 Piston is at top. Btw, you can only tap valves that are free, ie fully closed, turn 180 degrees to tap others, 180 degrees again two more times.

Valve lapping = Valve grinding or refacing the seats.
