Re: Topic: CLUNK!... crank locked up (Auto)

Sorry, my post was misleading so I've edited it now: " I should point out that it's still sometimes impossible to rotate from the crank pulley until it's been freed up front the torque converter end. However, last night it started up fine, albeit with the loud initial 'CLUNK', without having to...

Re: Topic: CLUNK!... crank locked up (Auto)

Very few people on here know about auto boxes. I had mine rebuilt be Lee at T2five all I can suggest is contacting him on Farcebook or Twitter.

Re: Topic: CLUNK!... crank locked up (Auto)

To narrow down the issue, how about removing the three flex plate bolts that attaches it to the torque converter. Then rotate the engine using a spanner on the crank pulley..... I should point out that it's still impossible to roate from the crank pulley *E D I T* until it's been freed up front the...

Re: Topic: CLUNK!... crank locked up (Auto)

I've been away so haven't had any time to spend on this, but in the last week I've managed to start up the bus and drive it locally with the mechanical 'CLUNK' getting a little stronger, and ocassionally having to to 'free' the torque converter by rotating it via the fins through the inspection hole...

Re: Topic: CLUNK!... crank locked up (Auto)

Right... it's been sitting for a month whilst I tried to find out where to get any parts I may potentially need. But after a quick phonecall to book it into the auto transmission specialist he suggested he could pop over to take a look before going to the effort of having the bus transported over. S...

Re: Topic: CLUNK!... crank locked up (Auto)

It locked up after a short drive of a mile. Drove normally, parked up, then went to move it after a few minutes stationary and it spun over noisily/rattly but failed to start. On second turn of the key it wouldn't turn over (same as at the start of this thread) and the crank is solid again... It doe...

Ha! If only... the engine was locked up even with the starter removed.

Worse still, after only 20miles of driving and a few uneventful starts... it's locked up solid again!!Β  :(

Re: Topic: CLUNK!... bus won't start (Auto)

Well...! After having spoken with an auto-transmission specialist, a trusted (Aircooled) VW mechanic, and the collective knowledge on here, my bus went off to a VW engine specialist on the back of a lowloader to either replace the flexplate or build a new engine... ...but after removal and finding b...

Re: Topic: CLUNK!... bus won't start (Auto)

Not yet - had a busy week at work and no time at the weekend to look. I spoke to a very good (Aircooled) engine guy at the end of last week who agrees it sounds like the flexplate. In fact I've just remembered I was supposed to call him back today after he'd spoken to a mate of his who builds Waterb...

Re: Topic: CLUNK!... bus won't start (Auto)

I'm not sure I understand - are you saying I can access the bolts and loosen enough to pull the engine away from transmission and then rotate by hand? I'll have to find a diagram as I'm not familiar with the flexplate or bolts! As an aside, I have a boroscope inspection camera at my disposal - is th...

Re: Topic: CLUNK!... bus won't start (Auto)

At lunch today, I called the tranny specialist that fixed the leak and he concurs that it could be the flexplate that's cracked, or that the engine has had it!... He confirmed they hadn't dropped the tranny for the work they did, so it's just 'one of those inconvenient things'. I wouldn't call mysel...

Re: Topic: CLUNK!... bus won't start (Auto)

The plugs and fuel priming all appear normal with the familiar one-second buz etc A little more info in case the problem could be tranny related? I had a seal replaced in the transmission less than 1000km ago at a specialist due to an ATF leak. I can't remember off the top of my head what seal it wa...

Re: Topic: CLUNK!... bus won't start (Auto)

No the engine does not rotate and feels physically locked solid.
Thanks for the pic, I was crawling around from the rear right corner on my drive, hence why I couldn't see it

Re: Topic: CLUNK!... bus won't start (Auto)

Yes, I had the plugs out when I tried to rotate the engine, to check for hydrolocking due to injectors.
I'll have another crawl inderneath to check the earth

Re: Topic: CLUNK!... bus won't start (Auto)

Right... I've had the starter motor out and it turns freely, I've removed and checked the spark plugs are dry, I'm pretty sure I had the gear selector in N when I tried to turn over the engine with a spanner on the crank nut... I haven't check the earth strap on the transmission simply because I cou...
