Question about Renault Cars & Trucks
I have recently purchased 2004 model Renault 420 dci premium truck(Chassis #:VF622GVA000134169)which has a problem with its engine. Can anyone tell us what should be the inlet and exhaust valve adjustment for the proper setting of the engine. Thank You.
Think their hydraulic tappets on this and you squeeze them in to remove the oil then when engine is started they will readjust themselves ,now if engine hasnt had regular oil changes they become gummed up and will not adjust.if you have the other type which are shimmed then go for around 12 inlet and 15 exhaust this setting will suffice for nearly all engines except some older 60s GT engines with high lift cams like the ford capri or a stag .Best engine ever built for commercial use was the gardner ,better than the rolls royce used in the guy trucks with the cheften head ,ascot on the front .Alas the only thing we make in the UK nowdays of which we produce many and thats home grown religious nutters

SOURCE: Engine tappet clearances
According to http://freespace.virgin.net/tommy.sandham/databook.htm# Rocker Adjustment, the cold clearance is .008" intake/.018" exhaust in the non-GT 1500cc, and .012" intake/.022 exhaust on the GT. Sweet little car!!!

Hi , the switch in the car puts the flap in the exhaust over for quick warm up and the flap in the inlet manifold is part of the ERG setup.The ERG flap works with the ECU and also when you hit the warm up switch .

Definitely. If you're lucky then only the valves are damaged and that can be repaired by removing and overhauling the cylinder head. The water pump will and cambelt tensioners will also need to be replaced as they're relatively cheap and if they fail after repair the cambelt must be removed again. If you're unlucky then the piston crowns have been damaged or even the cylinder liners and this requires a complete engine rebuild. If only the valves are affected then the engine can usually be successfully repaired at a reasonable cost, but it's vital to get the head checked for cracks and flatness before reassembly as the stress on the combustion chambers and valve guides caused by a belt failure can warp or crack the head.
If time is money for you, then it may be cheaper to fit a good used engine. Note that there are no cheap "reconditioned" engines regardless of whatever worthless guarantees are offered. If you go for a reconditioned unit then if you're in the UK make sure that the engine supplier is a member of the Federation of Engine Remanufacturers (FER). Don't just rely on the logo on signs and stationery, actively check with the FER as some dodgy outfits have no qualms about claiming to ber members when they're not.
A good used engine will cost around £160 or so, make sure that you can hear the engine running before it's removed from the scrapped donor vehicle. It's cheap, but a risky choice and you'll need to add the cost of an immediate precautionary cambelt and water pump change.
A "reconditioned" engine means nothing. It might only have been degreased, repainted and had an oil and filter change. Recon is often a con.
A remanufactured engine will have been cleaned and then carefully tested before being largely or even completely dismantled. It's then rebuilt to precise tolerances using new or remanufactured parts. Expect to pay around half to two thirds of the cost of a brand new engine; they're not cheap but they are far cheaper than a new engine and will be supplied with a really worthwhile time/distance warranty.
I hope that you get your van fixed soon and that the damage isn't too serious. If my reply has helped then please return the favour by rating my answer.
