Niva Peugeot diesel engines

Just wondering if anyone out there off roads Nivas with these diesel engines in and if there any good.

Mines a non-turbo.

The only thing so far i don't like the look of is the cam belt-wont be able to go in deep muddy stuff?

It seems like more and more cars and SUVs, whether Diesel or Otto, come with belt-driven timing these days....

IMHO, this could make up for a big source of problems if you're using your rig for truly hardcore stuff. That's the main reason I steered away from installing a Fiat DOHC in my Niva, I heard all these terrible stories about people cruising around while the timing belt snapped and turned their engine into scrap that I got scared...

That's the beauty of the standard Lada engine. It's a non-interferance design where the pistons and the valves don't share the same space.

If the timing chain breaks just replace the chain.

I couldn't agree more with John...

If only the R&D department at Lada would have given it a couple dozen more horses... Wink

It's not tuned for horses .... it's tuned for reliability.

I'm sorry to tell you but the standard lada engine (1700i) does share the same space, pistons and valves. I know this from experience, a car i recently brought was a non runner- suspect timing chain break in fact the tensioner had been left too long and the chain jumped a few teeth and the valves bent on contact with pistons..

There are loads of pictures of my 1700i (Burgundy) in my avatar on the nnoc web site and elsewhere on diff lock--search snorkel or winch.

I'm hoping the diesel engine Will give me the engine braking I'm after when going down slippery hills......?

Hi Paul:

I've never seen the guts of a 1700 engine. However, I felt like I had to check some things out now that my 1600 block is all stripped...

Pic NÂº 1 shows how much there is from the cylinder ridge up to the block's deck.

Pic NÂº 2, just for fun, fitted a piston ring under the ridge and measured using a vernier caliper.

Pic NÂº 3, a little blurry, 9 mm from top of the deck to right under the ridge. The piston sits a little higher though, but there's still lots of valve clearance.

Does anyone know the effective valve lift for 1600-1700 engines???

They've both got an 80mm stroke. The compression ratio is higher in the 1700's, 9.3:1 as opposed to 8.5:1 in the 1600. I don't know what the valve lifts are in either. But it's entirely possible the 1700 is an interference design.

You live and learn!

id been told by the Lada uk that they had never come across interference but i had good size print in a piston and bent valves. I was hoping to just put chain back on and new tensioner but the cam would not turn very far due to the bent valve.

I fitted a 1600 head and it ran fine, not give it a good run yet though.

Get yourself a digital vernier Alejandro!

Naaah, digital verniers are for very accurate measurements... I use it mostly for measuring pipes/tubing I.D. and O.D. at my business, so I guess digital is way too overkill for that...

I heard a rumor a while back that Alan Bird at Lada UK was making plans for a Pug diesel conversion. I don't think there are too many of them about in the UK though. I for one would like one, bring on the veggie oil Wink

theres is a bloke on the fiatforum who has put a 1900TD fiat tipo engine into a lada niva. from what i have been told the bottom end of the engine is the same as a twincam?

Hi,
Here in Portugal, most of the NIVAs sold after 1994 are PUG diesel.

The diesel engine is very robust and easy to find parts.

Long time ago I put the dreaded Nissan in a Niva. But in my search for a diesel I came across one that Motor and Diesel had converted to a Pug engine using a kit of bits from Lada France. The sump was a work of art being cast with all the right bosses to pick up the diff mountings etc. I seem to remember there being some diagrams of the later Pug engined Ladas on this forum some time ago with details of how to hang the diff.

Alan Bird did have one at his garage with a Peugeot in that he used around the farm, he welded the bellhousing of the Pug to the Niva seemed to work OK.

Dreaded Nissan????

Was this the 2ltr turbo diesel..Ive got one on the garage floor...to fit next.

If a montego engine has enough umph for S1 what about in a niva?

chrisv8 · Posted: Fri Dec 01, 2006 6:01 pm Post subject:

Yes Paul it's me again. Did you get the clutch fixed in the end ?

Back to the Pug conversion, Lada France developed a whole load of kit to put the engine in which I believe is what is used in most left hand drive versions. The problem with Rt hand drive was getting the steering in but M & D had engineered a very nice solution but it was very expensive. Paul has some info I think in the file with the car he bought from my son., via an intermediary.

chrisv8 no clutch not done, wish id never took the thing out and id be building that motor up now.

Its a future project for me as my current diesel pickup conversion is taking all my time up.
