Hi all
I'm
New here.
I'm on my second RRC and have landed a stinker.
Stripped heads on a cooked Vm engine and fitted new ones gaskets bolts etc.
Engine won't turn over except very slowly.
Suspected Earth leads etc. Cleaned and copper greased.
No change.
Now I'm
Starting to suspect stiff pistons.
Any advice?
I don't think it's the starter.
Starting to get a bad feeling down there in me pistons!
She started after a pull start. But won't start off the key, won't even turn over properly with proper charged batteries.
The orininal heads were very cooked. The clamping positions had sheared.
Blocked waterways and leaky rad caused the over heating.
Any advice?
Anyone and new pistons and rings if it is that road?
I'm going to stick with the VM as I'm in too deep already. Thanks

I have a 2.4 VM, that dont mean to say I know out about engins though.
However, I would have thought if the lump started and ran with a tow start then the engine must be somewhere near being right at least.
You say your batteries are fully charged, that's only half the test on a battery, they may not be capable of delivering enough grunt to turn your motor fast enough, perhaps get them tested at a garage. How long have you had it???
 
[hi Frog hopper
Only got it couple of months back. An eBay impulse. I believed the guy. A bad move. So shipped it to Ireland from Doncaster and it was bought as a non runner.
Vm diesel advised me on the heads. I thought it was just the heads gone.
Not so sure now.
I'll try turn engine by hand tomorrow and see if it's tight.
The batteries worked well in other Diesel engines, albeit not as heavy as the VMQUOTE="frog hopper, post: 4130828, member: 36422"]I have a 2.4 VM, that dont mean to say I know out about engins though.

I have experienced this with a VM, I'm the "spanner handler" for a mate who has one fitted in a LR County, the problem will be in the starter motor, the brush holder assembly gets loose in the end frame of the starter and it creates a poor contact to earth within the starter. The starter will need to be taken off, (a pain in the ar5e job), and possibly better if it is all stripped apart and overhauled, easy enough to do if you are a bit mech savvy, or pass it over to an "old school" auto electrician who knows his stuff. The repaired starter will spin it over a surprising amount faster.
As has already been said, if you can turn the engine by hand and it will start/run with a tow, it should be good to go.
 
Good man
I'll give that a go. I'll try the Engone by hand and fingers crossed it's the starter!
Thanks for this

Thank feck for that, thought I was going daft (er)
@Gazbo Thanks for the heads up on the starter, one of those things that will no doubt bite me in the bum a few years down the line.
Learn summat every day on ere.

So
To update on what happened.
I got the starter out, what a pug of a job.
Bench tested it and it started smoking from out the back.
To be honest I was relieved to find the problem.
I had pushed the jeep to enqsure that the engine was turning freely. So not seizing up.
Took the starter to an old boy I know and he rebuilt it for me. €110 and a pot of jam.
I was delighted.
So I'll try get it fitted next week and hopefully get it starting off the key.
There is a continuous small water leak from the bottom hose. I've fitted new jubilee clips, quality Ines, but I can't get it to stop.
Any suggestions?
I pressure tested the Rad. All good. Found two blockages in the smaller pipes so I'd say the engine wasn't run with coolant due to a slow leak.
Has anyone repositioned the rad reservoir?
It's just that bit too low for me or would it make any difference?
Thanks for all the help. Especially about the starter.
I was trying to upload a video with no success.
Any advice there?
Illlet ye know how the recon starter works out.

Bottom hose old cracked and leaking???
Water pump gone and leaking down hose, not sure of the plumbing????
Put vids on youtube and link on here.
:mad:JEEP:rolleyes:
 
Reap the creek in a wickliw j???
Anywho, I got the starter rebuilt and she started up after a painful refitting experience.
A lotta smoke. I'm not so impressed with.
Anyone ever redone the rings in a VM2.5?
I'll drive it round the fields for a while and if no improvement it looks like I'll be pulling pistob out of its bum and fitting new rings.
Hope the liners aren't too glazed
Thanks for the comments guys. Keep em coming
 
Might just want a run, my first range rover had a perkins 4236 engine in it and after spending about year off the road while I welded the body up it smoked awful for the first few miles then cleared.

I've left it running for a while no change. It's not insured yet.
I borrowed a compress ion tester so I'll see if the rings are good.
It could be diesel so I'll check injector spray too
 
When I bought my VM Classic 12 months ago the engine was alright but didn't exactly set the world on fire, and it did smoke a bit. Not having any experience of the VM I thought it was ok and I could see the little cap was missing off the FIP so assumed the smoke screw had been fiddled with. Anyway the rest of her was fine so I paid over my money.
The first 6 months were spent fettling various electrical niggles like heater fan, and changing the colour, in the last 4 months I have only done a couple of thousand km and pretty early on the turbo failed. Changed that for a recon one and everything fine except getting more and more difficult to start and producing more smoke on acceleration.
Someone on here (sorry can't remember handle) told me how to start it :eek::eek: ie wait another 10 seconds after glowplug light goes out on dash before cranking, that worked for me, just 1/4 turn and she fires up, but still smokey.
Nearly failed me on one trip, kept cutting out. Long story short it was sh1te in the fuel system, sedimenter was full of poo, cleaned out, blew out fuel lines, changed filter (again) cleaned filters in top of lift pump, what a difference, pulls better than my 200Tdi disco (tuned FIP) very happy bunny now, and NO smoke.
