As some of you know, I have a series 2 Landy as my daily wheels, I have been running an isuzu 2.8 diesel for around 5 years now and on 50/50 veg oil. The engine was high mileage when I fitted it -well over 200k, and was the first that appeared in my local scrappy, I got a lower mile engine later as a spare which I have just had to fit after the original gave up in a sort of high pressure explosion; It suddenly and without warning, blew oil out of every possible place it could, It was so bad that I could barely get the oil cap on with the pressure ;D ;D I have no idea what happened, but it still got me home about 6 miles and then properly gave up . I know veg oil in direct injection is a no-no, but was this the cause, or was it just at the end of its life? I have no regrets as I have covered maybe 30,000 miles on a £100 engine and run it on 100% veg in warm weather, so its been very cheap! The new engine is now in and ok, nowhere near as quick and smooth as the last, and I am now thinking of putting a mercedes 2.5 5 pot diesel in as these are veg friendly and bullet proof.....oh, and quiet! So any thoughts on this? I already have the merc motor, so just need to sort adaptors, mountings etc, lots of work, but no more than what I did originally to fit the isuzu........

Sell the diesels on ebay, put a proper engine in: You won't worry about the cost of fuel when you get to hear that every day

Do a search on the superturbodiesel.com forum. I remember a guy in Denmark (maybe?) on there mentioning that he put a Merc engine into a Landy.

Pull the old lump apart, that should give you a good idea of what caused its demise, if teh rings are all gummed and the oilways are all jellied up you can be pretty sure the veg had something to do with it...Merc 5 pots were no where near as powerful as the isuzu lump unless you do serious work on them. I'de be tempted to put the money into building a bio-d processor so you can run it in a DI without worry.

Which merc engine have you got, and what did it come out of? If it is a non turbo forget it, they are hopeless. Turbo engines can make 400+ hp on standard internals if you know what your doing.

I will pull the old motor apart, I took the head off expecting to see holed pistons considering the massive pressure, The oil looked ok when it shot out onto the road too. The engine I have got is the 2.5 non turbo 5 pot, I know it's not exactly going to light up the Tarmac, but I have a 190 diesel 2.5 and it's auto and it goes ok. Got lots of gears with 5 speed box and range rover diffs , and would guess they are similar weight? If the Landy pulled like the Merc I would be happy, it's all road use and I rarely tow unless my brother crashes his car ( about once a year)

dodgerover, Isuzu 2.8 turbo engines are rated at approx 80bhp from the factory 20+ years ago, the Isuzu 2.8 turbo intercooled from the Vauxhall Frontera had about 110bhp when new, the Mercedes 2.5 five pot turbo intercooled had 160(ish) when new. Which is why I too am looking to shoehorn one into my 2004 Trooper to replace the 2.8 4Jb1 that I have to replace the original 3.0 4Jx1.

On perusing your first post, I may have an alternative for you which might work out cheaper. Find yourself a 4JB2 Isuzu engine, 3.1 liter capacity and indirect injection. It'll bolt up to the same engine mounts as your current 2.8 using the same bellhousing and (I think) same flywheel and clutch.

It was the original normally aspirated merc 5 pots I was thinking about, they would never set the world on fire, The Isuzu 3.0 motor was never anything but trouble was it, a friend bought one nearly new after running an old one into the ground, he ended up very disappointed
