is 5 deg BTDC ok?

tpunx99GSX · 05-03-2007

I actually torqued the tensioner, but it ended up lining up at 5 degrees BTDC instead of 10. Is this ok?

**Shane@DBPerformance** · 05-03-2007

Huh? What tensioner, what is at 5 degrees BTDC? If you are doing the timing belt, then the crank should be at 0 degrees BTDC.

tpunx99GSX · 05-03-2007

All the guys on the dsmlink forums said that timing should be set at 10 degrees btdc, so that is what i set it at.
I should just change this topic to "Car wont start"
With the timing at 5 degrees BTDC the car is getting spark out of all plugs.
All of my dsmlink settings are correct.
I am getting fuel pressure to the rail, but i dont know how to check if the injectors are firing. The reason i am even considering this as a possiblity is that the injector electrical plugs are worn, Im going to replace them tomorrow. When i say worn, the plugs look like shit, and the wires are exposed.
The car keeps turning but wont fire up. The timing was off a lot before i did the timing belt this time, but now its dead on and still not firing.

Not all of us are members of the DSMlink forum.

What it sounds like they're referring to is the timing of the cam angle sensor, which is how the timing is adjusted, not by adjusting the timing belt tensioner. I think you're chasing the wrong monkey up the wrong tree.

That post is refering to your ignition timing. it should be set at 5 deg with the grd timeing box checked in miscilanious or the plug on the firewall grounded.

If your setting your cam timeing (timeing belt) there is a pointer on the oil pump housing that aligns with a mark on the crank.

**Halon** · 05-03-2007

Ya I'm confused on what you're saying you set to 10* or 5*. You put the belt on in such a way that all your marks line up.

Then you change your base timing (degree) with the Cam Angle Sensor so you're at 5* BTDC with the timing plug grounded.

acidrumz · 05-03-2007

yeah you got it... you can adjust the base timing to whichever degree you want by advancing or retarding the cas. but make sure your tdc is at 0 after your set your timing belt..
later.

Don't confuse ignition timing, cam timing and actually lining up timing marks when doing a belt. They are all different things.

tpunx99GSX · 05-03-2007

But even if i had it at 5 deg btdc on the crank it should still fire right? It was firing at 10 degrees btdc when i installed the motor originally.

**JET** · 05-03-2007

Tom, can you clarify some more? I think you have most of us confused now. Which timing are you trying to do? The timing belt should be set at TDC and the ignition timing should be at 5 BTDC.

Did you do a compression test? You should see if you have bent valves from the last problem.

tpunx99GSX · 05-03-2007

Yeah i set the timing on the crank at 5 degrees BTDC. So ill have to change that to TDC.
I havent done a compression check yet.
Tonight when i get home im going to go over everything and change out the Fuel Injector Electrical plugs.
Would bent valves cause it not to start, or would it just run like crap? The car will just continue to turn and just wont fire, I have spark. I dont know how to check whether the injectors are firing.

**JET** · 05-03-2007

Bent valves could cause it not to start. You should be able to hear or feel the injectors clicking when they fire.

tpunx99GSX · 05-03-2007

otherwise couldnt i just pull out the spark plug and shine a light down there and see/smell the gas going into the cylinders?

A//// Guy · 05-03-2007

Well if it was running before why wouldnt the injectors be firing? Your bent valves could cause a drastic loss in compression and the engine just wont run because of it. So do a compression test first and see what the numbers are.

Got safety glasses?

Kevin 1G Drummer · 05-03-2007

You could just pull the plugs after cranking it a while with them unplugged. If it's getting fuel, they'll be wet.

carltalon · 05-03-2007

I just want to know how you can set a timing belt to 5 deg BTDS. are you seting the belt with the timing cover and the damener on?

I'm confused

tpunx99GSX · 05-03-2007

Well my car is broke once again. I did a compression check and have 0 Compression. Absolutly none. I will be ordering new valves this weekend.

**JET** · 05-03-2007

Your guides are going to be shot too, better get the head to the machine shop. Replace valve seals while you are at it. Are the tops of the pistons ok?

It sucks when that stuff happens, it is part of the learning process though.
