For the engine to be set to the factory recommended degrees of timing you have to pull the distributor adjustment bolts out to get enough play of twisting the distributor.

Here is a list of what has been checked.

The crank pully TDC mark is actually not correct, its off by an inch or so (did it twist on the harmonic balancer?) But either way, pulled 1st spark plug and put in screw driver and found actual TDC and put new mark on Crank pully

Timing is correct, nothing is off by a tooth or anything strange

The key way on the crank and cog are in perfect condition

Distributor keys into cam offset only one way so that cant be off

New cap/rotor (is it possible a SOHC cap could have been given to me and it fits and is twisted slightly more than a GT?)

Good compression (200ish on all) and fresh head job so no leakdown

Its got me and all my friends confused and we are just scratching our heads now, maybe somebody put on a different distributor?

what is the recommended ignition timming @ how many rpms?
first remove crank pulley and check timming with all timming belts pulley, allign crank accurately and check timmings marks on camshaft sprockets and post a picture

you can remove the bolt of the intake camgear to see if it correctly instaled with dowel pin on the camshaft

I'd like to know what is the problem with your car. You talked about a bunch of stuff that you did but you never told us what your car is doing or not doing.

Oh and sticking a screw driver in the spark plug hole to find tdc is NOT HOW THESE ENGINES ARE TIMED.

First line, you have to remove bolts holding in distributor to get it spin enough to time correctly

Got a better way to find TDC on an engine with the head installed and pulley with a screwed up mark?

Yeah, remove the pulley for the serpentine belt, line the dot on the front of the timing gear with the dot on the oil pump. problem solved.

Exactly. You line up all the timing marks like your supposed to and then use a timing light to adjust the distributor. And THEN you can use the little notch on the serpentine belt pulley with the front of the timing cover to set timing to 5degrees.

The distributor should only rotate maybe 30 degrees for adjusting purposes.. If you are that far out then your timing marks on the crank pulley and cam pulleys are way off.

Touche haha Guess we just didn't want to take the front half of the motor off when the latter was so simple.

I need to get the car back here and dig back into this timing

Yea its way more than 30 degrees, its gotta be something like the pin in the cams or something. I need to get a new crank pulley also to rule that out of the equation. Sounds like its time for an aluminum one haha

BIGOLBUMP

Still have the same problem and it is driving me insane at this point.

(Sparknotes)
All pulleys are lines up correct and its not off by a tooth.
Keyway is fine
compression great

Crank pully has "new" tdc mark (while inside bottom timing gear lined up correctly new mark was made on crank pully exterior)

And this is what it takes to get the engine timed correctly
Image

Wrong distributor? Possibly a single cam distributor cap? Are the 3 cyl distributor screw in point diff/maybe I have one on my motor?

Im completely out of ideas at this point

Do your cam pulleys have two different dowel pin spots? Some Suzuki pulleys have two different dowel pin spots depending on whether they are on the intake or exhaust cam. Perhaps you have a pulley on the wrong dowel notch. May have to pull the cam bolts to confirm this, don't think you will be able to tell with the bolts and washers covering the centre of the pulleys when they are installed

Or is the distributor housing simply flipped around wrong, with the cap and rotor all aligned properly? Wondering what would happen if you pulled it out and spun only the housing 180 degrees(rotor position won't change), I think you will have to reroute your plug wires in order to flip cap 180 degrees as well

The flat spot and casting line in the pic would be indicators of housing alignment, I just don't have a gti motor in front of me to check whether those marks are normally at the top or are underneath on a proper gt aligned distributor. Anyone looking at a gti engine right now??

Yep, and they are on the right ones, have the pic on computer just forgot to upload those two

I thought about that, but didn't try it, distributor wires sticking out the top wasn't right, i might try that tomorrow just because why not.

The rotor can only go on one way so thats right, and dizzy can only index into cam one way

Here is intake cam, lined up, and the dowel in on the bottom on the "I" hole (not visable but not in the E hole that is visible)

Image

here is the exhaust, lined up and dowel on the bottom in the "E" hole (not visable but not in the I hole that is visible)

Thanks for all the help so far, i will try those couple little things tomorrow

Wires on are correct on the cap
SOHC and DOHC caps are different and I have the DOHC cap so thats right
Looked at pics of people engines and the wires do face the bottom of the distributor.

:dunno:

update, thought maybe it was an idle issue, held the throttle at like 2000-2500 somewhere around there and moved the timing on distributor back to where it should be and clug clug dead. so not an idle issue

Welp....sometimes if you have ruled out everything but one thing....its that one thing. My distributor was fubar

My known working second hand distributor IN BOTH PICS THE ROTOR IS FACING THE SAME WAY
(note position of the reluctor ring to the pickup....)
Image



And this is the bad one (note position of the reluctor ring to the pickup this time)
Looks like the reluctor has spun on the shaft, Makes perfect sense...why it happened,....who knows, i bought it with a bunch of issues
Image


What a total pain in the ass this whole adventure has been hahaha
Thanks for all the help guys, what a weird thing to be wrong.

Just a thought, have these distributors have some kind of mechanical advance or electric advance mechanism built in to them, if so could it be stuck in full advance?
