Hey guys I have a b18c1 that I just rebuilt top to bottom. I had spun a bearing on my way to work one morning due to lack of oil pressure. I'll start off and tell you what I've done to it. New oil pump, bearing, water pump, .040 over p73 pistons new rings. Had the block cleaned and bored out .040. Top end I went with complete super tech valve train ( new valves dual springs retainers and guilds). I have blox stage two cams with skunk2 cam
Gears and a skunk2 intake manifold with Rc 310 injectors.

Now my problem is I finally got everything back together last night and tried starting it for the first time. Btw this engine is in a eg hatch. It tried starting but backfired out the intake. Messed with timing thinking I was on the wrong stroke. Changed my timing so now I back
Fire out my exhaust.

Now I know that my timing could be it but any ideas what else it could be or maybe someone else ran into this problem and can help tell me what to look for.

Did you check mechanical timing or ignition timing? Backfiring out the intake is almost always wrong ignition timing.

Eghatchgsr8

Just mechanical. How would I do ignition?

Also can't the dizzy only
Go on one way cause of the teeth. It's not like that could be off or could it?

I bet your dizzy is 180 out! check the dizzy!

Eghatchgsr8

I don't know this might sound stupid but can you do that on these engines? I thought the teeth can only go in one way.

wunfstgsr

Yes it will go on but not smooth but still be 180 out, i did it not to long ago when i rebuilt my dizzy. I believe i put the chuck on the dizzy shaft reversed, just pull it out and turn it 180 and put it back in.

"copied from a old post",

you cannot I repeat cannot install the dist 180 out unless you install the chuck on the dist shaft reversed. the chuck is staggered toward only being able to fit on the cam one way (whew) what a relief. this is super true. not just real. I know I am tired. your belt could have already slipped if it is 180 out. brings back funny memories about two tegs and a green mustang, one bad rotor screw and two temporarily downed integras. fun fun.

oh yea, if the intake cam slipps 180 out... guess what? the compression stroke pushes the air right through the intake manifold! hence, no compression! and no start-y!

Distributor cannot go on 180 out without breaking the chuck (at least I haven't seen it) make sure the spark plug wires are in the right order for the firing sequence

"you cannot I repeat cannot install the dist 180 out unless you install the chuck on the dist shaft reversed" but it can still go on with a lil force iv done it by accident my self lol

Alright well I'm gonna work on it all night tonight didn't get to last night cause I was super busy. I'm gonna make sure clave clearance is good along with doing my timing again. I have a msd set up and I hate it. I was thinking about going back to stock(msd came with the swap when I first got it). I'll let you know what happens. Hopefully it fires up

Eghatchgsr8

Ok so I I tossed the skunk2 cam gears and went back to stock. Retimed it adjusted my valves. I have fuel and spark. I tried starting it and I got one super loud backfire. I tried again. Retimed it. This time I took my cap off and with cylinder at tdc my rotor was pointing at cylinder 3. Wtf?! How does that happen. I don't know if I said this either but I have this pos msd set up. But it worked before I spun a bearing. I don't get it

wunfstgsr

I believe it should be pointing to #1 that seems to be your issue. Are you sure the cam gears are properly set to tdc? post a pic of the cam gears aligned and that MSD dist. And i would also toss out that MSD and just use a oem dizzy set up again.

Eghatchgsr8

Yeah it is supposed to be on one. I don't get it. I had this set up working before I rebuilt the engine and now I'm off? That doesn't make sense. I already ordered a new dizzy will be here tomorrow. It's to dark right now so I'll have to take pics tomorrow. Ima throw the new dizzy on and see what happens. Also gonna do a compression test

Eghatchgsr8

It was the dizzy! Replaced and fired right up! Now I get this weird sound at idle. Like woob woob woob.

wunfstgsr

hmm i wanna say i heard that sound before lol but post a sound clip and try pin pointing where its coming from like head block or tranny or wherever. could be anything.

I have seen aftermarket (auto parts store) distributors that could be installed 180 degrees out. The teeth on them were not sized differently like the OEM units are. I know you already figured out the problem but figured I'd post just in case someone in the future finds this thread while troubleshooting. If your distrinutor isn't OEM its definitely possible that it could be 180 degrees out.

Eghatchgsr8

Thank you everyone!

wunfstgsr

Did you get the woob woob sound figured out?

sowellman88011

did you put the adjustable cam gears back on? Im sure those cams need to be degreed. if you did put them back on and degreed them then is it the sound of the more aggressive cams?
