another engine swapping thread.

Jan 28, 2005 12 Replies

Recently I've been fitting a proper engine to a 1985 Land Rover 90.



Basically this means I took the horrible diesel engine out, and replaced it with a 3.5 V8 from a Range Rover.



All the mountings, flywheel etc and the bellhousing were taken from a dead Landy with a V8 fitted.



Now, here's the bit that's confuddled me.



When the engine was out, it turned over beautifully, I fitted a new clutch and put the motor in. Engine still turned over nicely, clutch works as it should. Fitting the engine took some time as it was basically just being done in bits, the occasional afternoon when weather permits. Carbs etc all fitted, oil pump primed, went to turn over the engine to TDC to fit the distributor...



,, and the engine is locked solid. Won't budge. Even tried towing it with another car and it's solid as a solid thing.



Clues please? I'm really not looking forwards to taking the bloody thing back out in order to start again.



Leaky head gasket that's filled a cylinder with water?

not put water in it yet....

was just in the final stages of putting all the ancillaries on first, distributor, then it was going to be leads, then the rad..

Dizzie drive the right type? May be able to lock up an enginee....anyone?

I think you'll need to look at this in order - did it turn over after you'd fitted the gearbox? Did it still turn after fitting the gearbox and pressing the clutch a couple of times?

I really would advise against trying to tow or shock it free - it's almost certainly something mechanical locked and forcing it will break whatever it is.

Using a spanner on the front pulley, will it turn backwards? If it will turn a way backwards then lock again, it's probably either the cam timing out, or a rocker (or several) with insufficient free movement and the pistons are fouling the valves.

Thrust bearings is a thought - if actuating the clutch has caused it to lock, maybe it's shifted the crank forwards and locked it?

The other possibility is that you've left a spanner in the sump and it's jamming one of the webs of the crank!

Yep.

Well, you're right, but you know what it's like when things get annoying.

Nope, it's solid.

Maybe

Not taken the sump off, the engine was complete bar carbs, waterpump and dizzy.

:-) Only too well!

Hmmm... Probably not that then. Good.

How careful was the rebuild? Were things like crank thrusts and runouts measured?

I suspect that my next job would be to remove the starter motor, spark plugs (just in case) and the sump. Testing the engine with a spanner to see if it turns in between each removal. Eventually the engine will be in bits again, or working!

though I'd expect that to break if you tried towing. is it solid backwards as well?

Were all your tools and sundry bits accounted for after you mated the engine to the gearbox? Something might have found its way into the bell housing (like a nut or something) and lodged between the starter ring gear and the casting and is now acting like a bi-directional spragg clutch!

I'll find out next week. Everything seems to be present and correct though..

I must be mad, I might be swapping the Merc for a 92 3.9 Rangey tomorrow..

I must have murdered priests in a previous life or summat.. I don't deserve this!!

nah, the 3.9 RR is the canine gonads. 'specially if it's a full-spec vogue with leather and aircon. lovely motors. convert it to LPG (unless it is) and it'll cost about the same to run as a TDi.

I used to have a lovely Vogue SE about 8-9 years ago. Unfortunately this one is just the Vogue. No leather or AC :(

Wrong starter motor jamming the ring gear?
