Crank / No Start Solved. Now 1222

[JerEazy]

Idle is a little low for my taste and gives a shake. But she runs beautiful under throttle.

wonder if I’ve got an ECU issue....

[JerEazy]

Swapped plugs and didn’t help. Did another smoke test to confirm and nothing leaked.

swapped AFM and started it. She bounced around quite a bit but after about 30 seconds steadied in...

TPS adjustment has been checked and confirmed....

Went from a died while driving to a crank no start. Did some searching and confirmed fuel, confirmed compression, spark was the issue. Doing some quick reading of things I can test/replace...

[JerEazy]

As expected - still crank/no start. Will start new thread....

[JerEazy]

Ok. New seals are in and smoke test came back clean. Only smoke from the machine was coming out of the exhaust.

Will button the rest up tomorrow.

Did timing belt, new water...

[JerEazy]

Ok - they are deeper - the back of them is flush with the back of the housing. I could push them back the other way a bit. And yes, that’s a lighting/angle issue on the oil pump seal. It is uniform...

[JerEazy]

Ok. So I’m thinking my issue was I left the front seal for the crank and oil pump more or less flush with the cover. I made a point to seat them a bit deeper. The backs of the seals are basically flush...

[JerEazy]

before I reinstall I am going to post up a picture of the seals installed so i can get thumbs up from the pros on its setting. Currently awaiting delivery....

[JerEazy]

I dont think the gear sits flush against the seal otherwise it would just tear the seal as soon as it spun turned over? Not sure. And there wasn’t a leak at installation and after test drive (did a...

Got the front cover and harmonic off. Something went or was bad. The spring/metal inside the seal came out, wrapped around the crank nose, marred the back of the balancer and the nose. If replaced...

[JerEazy]

Doesn’t the tube from the intake go to the crankcase too?

Mine would stumble and almost fall off with oil cap removed. Would get a little “lope” with dipstick out.

I ordered...

[JerEazy]

I have confirmed fuel. Was the first thing I checked because it felt like it ran out of gas. Will confirm spark tomorrow AM.

I was reviewing the video of the smoke test from...

[JerEazy]

Compression test done and all within a few PSI of each other. Don’t have the tool for a leak down - but could go get one. But I don’t think that’s causing my no start. Been in and out of this...

[JerEazy]

I used elring last time and run 20w50...

[JerEazy]

I would assume a bad seal and a big vac leak would be a problem and cause a no start issue. Am I wrong there? It’s the only place putting out smoke on a test. Car literally went from running, to...

I have now had 2 front main seals go out on me on my 1990 BMW 325i M20B25

First time MAY have been my fault from poor install. Kinda half assed it and rushed through. 2nd time no way. ...
