Hi everyone. I am new here but by all mean, long term tech. I am being a little cheap at the moment and do not want to go with aldata.

Story on car. Customer 1995 civic DOHC car was running fine one day shut off engine and did not start it again for another two weeks. The car then would not start.

Cranking the engine, the Engine Did have uneven cylinder compression. I loosened up the rings with carbon cleaner and now the cylinder compression is even.

The engine did not start, so checked these items:

Timming belt was by what may be 1-3 teeth! at least, what it looks to be off.
With #1 cylinder TDC with 1/4 inch extention in hole. Crank harmonic ballancer mark is what is shown in this photo. Shouldn't the timing be on the red mark in-between the two other marks next to it? It is on the far right mark. What are the group of thee marks for vs the one mark by its self on the harmonic ballancer?

I have the white mark lined up and #1 cylinder at TDC. But again, the distributor rotor is off 15- 20 degrees..to the edg of the cap terminal.

I suspect the belt jumped time. But the belt, while a little loose, was not excessive. If in fact it did jump time, what would cause it? bad plugs, weak battery low compression from stuck rings caused piston/crank kickback causing belt to jump time? Is it common with neglected maintenance for the timing belt to jump time?

Anyway, just want to know timing specs for this motor. It is the DOHC 95 civic model.


Thanks

I don't think any regular Civics got a DOHC.
You must either have a Del Sol DOHC or you have an engine swap. What is the engine out of, if it is a swap? What are the engine numbers?

You also posted this in 7th gen, which is 01-05.


Rule #1: The distributor shouldn't ever need to be touched (unless someone touched it). If timing is out of whack, look everywhere else.

On to the timing belt....
Trust the extension. Look at what mark is up when the extension reverses direction.
The white mark is TDC. You need this one.
Red mark is the BTDC timing mark for ignition timing. This mark is all you need to set timing (after you put a jumper in the SCS connector.) The other 2 marks close to the red are the +/- 2 degrees from spec.

Make sure you are turning the crank the correct direction (CCW).

This visual is meaningless by itself. What did a timing light flash on?

If ignition timing was 20 degrees off when using a timing light, then my first thought is that cam jumped a tooth. Pull the covers off and start digging.
