LPG V8 110

Jan 05, 2004 8 Replies

I've seen a few 110 station wagons with a 3.5 V8 and an LPG conversion, vehicle age being around C plate UK (1986 ish?).



Is there anything I should be watching out for on these engines in particular? I've no experience of V8's, I'm more a diesel man myself.



Should I budget to have the LPG systep professionally checked? And the engine tuned/set-up properly?



Why am I finding them cheaper than diesels? is it just because they are unpopular due to thirst?

excessive cam noise, really, and *seriously* low oil pressure. They run very low oil pressure anyway, mind. If it has a gauge, hot oil pressure should be 30-40 at 2400 revs (which sounds quite fast on a V8!) and shouldn;t really be under about 10 at hot idle.

checked, yes. engine tune-up is rather optional, if it runs well and returns reasonable economy (mine, with auto box, does about 11mpg on gas, you're unlikely to get more than about 14)

yep. especially unconverted ones. Keep an eye out for 4-speed gearboxes, on early 110s, which are worth at least 500 off the price, not 'cos it's a bad box but cos it's not got the high 5th gear.

bodywork-wise, the "C" post behind the rear passenger doors can rot, making the whole back bodywork sides flexible. That's about the only SW-specific body problem, other than of course twice the number of doors to rot and windows to go wrong...

Are the cams on top and so easy to hear?

The ones I've seen have the 4 speed box, how hard is it to put a 5 speed in?

I'm shopping at under £2k so I'll not get £500 off, it'd be worth the price if it looks solid enough and has LPG. I think....

Indeed. The SW specific crossmember at the front of the rear tub also rots badly...... and of course the back door is most likely to be shot as well :(

well, the cam is right in the middle. But the noise is typical tappet noise, as of an engine which needs its tappets adjusting. Don't be fooled by vendors who try to claim that it just needs adjusting, the V8 uses hydraulic lifters, and they ain't adjustable.

the good news on V8s is that a decent secondhand engine is typically about

200-400 quid. If you find a good body with a naff-sounding engine, beat 'em down enough to cover the cost of buying and fitting an ex-Rangie 9.35:1 compression engine, which'll run better on gas anyway than the lower-compression one which is standard in the 110.

Straight engine swap is easy enough, no more than a day's work for a competent shop. 2 days max. Last time I pulled the engine on mine, it took about 2.5 hours to get it out. Mind, the putting back took about 2.5 days, but that was 'cos of all sorts of misalignments, caused mostly by the fact that the original engine I had was a very early one ex-P5B rover car, and had different pulleys and so on.

Are all the engine mounts in the same place? will it go straight onto the gearbox? what about the wireing of the ecu?

no ECU on a carb engine. Of course, if you go for an injection one you need the ecu and stuff with it. mounting to gearbox not a problem, and if the engine mounts or manifolds *are* different, you have the ones on the 110 to swap to the engine yer putting in. Only problems I've had are silly things like different front pulleys Rangie vs. car, meaning that belts didn't line up or were too long, but that's less likely to be a problem. I guess the front pulley could have been changed, too, if I'd been bothered, but I preferred in this case to get everything fitting an RR spec engine.

The RR's I've seen around are all EFI's.... though I'd prefer injection... on the other hand is there a website I can learn about carbs from an idiots perspective?

Is it easy to find replacement crossmembers to weld into place?
