timing off, bending valves?

[Neejay]

My timing is off and the car cranks, but won't turn over.

If I keep adjusting the dist./timing, which includes repeated cranking, how likely is it that I'll bend a valve(s)?

I'll be taking it to a local shop here soon...I'm tired of fucking around with it.

EDIT: KA24DE, did 248/232 cam swap, marked everything before hand with engine TDC, 248 cam turned CCW per numerous How-Tos

Ignotion timing cannot bend valves. Your cam timing would have to be off to do that, but if your timing chain is loose enough to slip you wouldn't have posted this thread because it would sound like someone threw rocks in there. Do you have spark? Do you have fuel pressure? Are the injectors firing?

Sorry, I should have given more detail. I did a 248/232 cam swap. I marked everything before hand on the distributor (while the engine was at TDC). Put everything back to gether, 248 cam @ 4 teeth CCW (per numerous How-Tos).

I mean, unless my injectors, wires, and/or coil took a shit after I put everything back together, everything was running fine before hand...

KA, SR, etc....?

[Neejay]

KA24DE, I'll edit the original post with the added info..

[racepar1]

So you're saying that you set one of the cams 4 teeth off? And you got that info from install write-ups? I hope I am mistaken here.

[S14DB]

Told you that you should have had it at TDC before you removed the cams.

[racepar1]

You need to take it all apart again and set the cam gears up according to the OE timing marks. Hopefully you didn't bend any valves! Those durations sound very similar to the OE s-13 cams, do they have more lift?

For the 248/232 cam swap, yes. You rotate it CCW 4 teeth. That also places it in sync with #1 cylinder being TDC (both intake and exhaust cam were facing away from the #1 cylinder). 4 teeth counter-clockwise puts the 248 cam in the same position as the stock intake cam.

I did. I know I did. Now, whether or not something got moved during the whole process, I don't know...

They are.

It's the exhaust cam swap or something.
I forget.

but..
hm.. Nick.. I really hope you didn't bend your valves.

BUT, if your dizzy timing is right, check coil, grounds, and power.

It's taking the s13 248 exhaust cam, making it an intake cam, and using the s14 232 exhaust cam, and making it a s13 exhaust cam.

I'm not doing it again, especially without a garage/personal driveway + working full-time. I'll pay someone before doing it again.

Me too...I don't know what I'd do at that point (engine wise).

My last resort would be to replace the dist. cap and rotor and check the coil...bah...

[babowc]

well,
try what you can before you resort to a shop, anyways.

maybe Russ can chime in..

You can use the s-13 exhaust cams for both, why didn't you do that out of curiosity?

Just do a compression test, that will verify if the cam timing is good or bad.

Then, unplug the tps, and pull the fuel pump fuse, have a friend crank the starter, while you flash the timing light at the crank.

That should clear this all up real quick.

[louisdaboois]

im sure if youve been turning the motor over and the valves havent bent by now, you should be in the clear. the ka igition timing is hard as hell to set, i'd say turn the rotor and stab it in again.

hmm...thanks for the extra option. I'll try both of those before taking it to a shop.

That's the problem though, I don't know how to tell if a valve is bent yet :(

This is how it was last time before I bolted everything up/on. When I took everything off, the timing chain wasn't in the same place I put it (even with everything TDC + distributor marked correctly this time).

This is currently how it looks, TDC, teeth correct. The thing is, I can't put the chain and sprockets on without the chain slack seemingly being on the wrong side. My guess is that the pressure from the tensioner causes the chain to "settle" which means it jumps teeth to get into place.

Looks like the chain jumped teeth the last time. Bent valves?

EDIT: I didn't do the compression test first because I wanted to check my work first.

I can't see the lobes, but the dots are looking way off if that's TDC.

You need to get it to TDC (at this point I'd verify with a dowel in the #1 cylinder to make sure the piston is definitely at the top.

Then get both cams to point out.

The pictures at JWT's site is excellent. Look up the cam installation doc.

Whatever you do, HAND CRANK it first.

It's cool, I ended up taking it to a local shop. Didn't know what else to do + limited time + no garage + full-time job.
