FML Seized M50

[Mr.SWISS]

first off, with the G260 you cannot get to the bolts in question with the trans in place :( Second, they are a long bolt with a cast in boss that is part of the pan, this is why it hits, it isnt just the bolt, its the pan as well. third, yes, it can lock the motor tighter than a bulls ass due to the interference.

And there is the problem and why if you run a 260, you deal with the extra bullshit. Shave back of pan and or flywheel, get custom trans mount and shifter setup, deal with only 4 big bolts holding it all together...... :crazy:

Or 240,250, and ZF fit fine and go all nice and simple.

The cap will most likely disintegrate upon the first combustion cycle.

Sounds like your flywheel is binding.

Are you 100% sure it's timed correctly?

[Hey_You]

So you had tried turning it over the first time, but think the engine was turning when you put the driveshaft in? Was your trans in neutral? That's my guess. Also, do as these people say and shave your flywheel. There MUST be a reason why they suggest doing that

[gkobez]

How long, and where was this engine sitting? Before you got it and while you have had it?

[TimKninja]

No I didn't. Ive only heard this is required with some people's swaps. I swear it was turning before when i was putting the driveshaft in. If I remove these oil pan bolts , would it theoretically spin? As a process of elimination thing. Now if it does spin after that I suppose the engine and tranny are coming back out to fix that . And you say it will bind, but I cant even get my crank to move at ALL.

[scottinAZ]

you DID shave the back of the M20 flywheel didnt you????

If not, you are binding on the two rearmost oil pan bolts, and the back of the flywheel. common problem.

[TimKninja]

I removed all the plugs , so I dont think I'm getting hydrolocked, this is my first attempt to crank it.I had to switch out from the m50 starter to the m20 one. The m50 doesn't mesh . Im using a single mass M20 flywheel from an 85 eta, and clutch and a getrag 260 from an 88 325i.

So you dont think the cap needs to come out?

[Mr.SWISS]

Yea that plastic cap is not going to seize and likely will get mauled and burned to a crisp on it's exhaust gaseous exit. You could be getting hydra locked by the oil filled cylinder. Also what clutch and fly are you using? Has this engine ran in the E30 before or is this the first crank you discovered all this?

[cabriodster87]

The only thing that comes to mind is something pinching/binding on the flywheel, and maybe some well placed compressed air will expel that nasty little cap, but that's the least of your problem. Let us know how it goes.

[TimKninja]

SO I just wired my car up, 85 ETA, 93 M50TU out of a 525i.

Had to replace starter, put new so starter in. all im getting is the Thud from the solonoid. Im thinking I have a bad starter. SO I for shits and giggles try to turn the motor by hand.

Wont turn with normal 22mm Wrench...okay Try a bigger wrench
It wont fucking turn with a 3/4 Ratchet .

Take out all the spark plugs, found out that when I let my friend do my valve cover gasket he left out one of the inner nuts...So Cylinder number 6 spark plug is submerged in oil.

In some twisted fatefull act, i was spraying PB Blaster into the cylinders to see ...AND THE FUCKING NOZZLE BROKE OFF AND DROPPED INTO THE CYLINDER.

FUCK.

So...I guess im asking, is their anyway to unseize my engine. It was turning a few weeks ago when i was putting my driveshaft in. Im 99% positive it was. an then ive been working on it in my free time (GO to school, Work two jobs) . So ive been working on it while I can. Ive pulled the intake mani to get at the starter. ANd I noticed some buildup above the valves, so i sprayed them down from the intake port, this wouldnt cause premature rusting of the cylinders?

And then while the intake mani was off and i was getting a new starter I let the car sit for two days til I got free time again, with the hood closed, intake manifold off and rags in Cylinders 1,2,5 and 6. Theres no way it coulda got wet in there?

My clutch isint bled right now, theres no possibility thats related.right?

Could a driveline misalignment cause the engine not to spin?

Theres no way of not pulling the head to get that cap out, is there? I cant leave that in their, can I?

Fuck This is terrible. I really need help. ive dumped all mty money into this thing only for this to happen.
