I've seen that once before. The engine had been rebuilt under warranty by a renault dealer and the pistons fitted the wrong way round. When aftermarket cams were fitted it became an issue and the valves clipped the pistons lightly and made a horrible noise. Unplugging the VVT solenoid stopped...

bit extreme to send it to oselli for cleaning!! i bet there's at least 5 engine reconditioners/engineers in or around bristol who could put it in their tank

differences between ph1 and 2 (extra bit on 1 corner of a ph1) but that's about it for anything important

should be ok if it's that new.

renault solution. I've removed washers due to them causing worse knocks and more play

dont bother. biggest waste of time going. small bit of grinding and it's solved

autosmart TrebleX. It's descaling acid, same as the concrete disolving stuff stan told you about. Just wear gloves and glasses. it stings like a motherfucker

well if it's getting upto temperature better it will be coming off cold start fueling easier. If it wasn't getting hot it would have been running rich and probably bogging down a bit. I'm hoping it's had a new aux belt at the same time ;) so that would have solved the belt slipping

inertia switch, cuts the fuel pump in a crash. Sometimes trips for other reasons or if it's disturbed. It's next to the ecu/battery

red button under the bonnet. push it

they're the same, might just be an updated part, or sourced from a different factory. Same pump as a mk1 1.8 16v and a williams too

you have the standard upper mounts? do the same thing as i said for the uprated items, slacken it all and re-tighten (dont have to remove the bolts, just undo them a couple of turns. It may just be that your upper mounts are worn out though

Auto data also has the torques wrong for the pulley bolt and nut

As said, anyone can learn it, just those who focus on one brand of car tend to invest a bit more time, effort and knowledge of the specifics into the job. For example, the procedures in Autodata for the F4R are wrong, and most places will go off that (I use renault tech documents) There's a lot...

Laser pins are fine, but the cam alignment bar bends (it's not even hardened!!!!!), and a pulley locking tool doesn't exist at all

disagree all you want :) I'm still right ;)

agree 100%. Even though Renault give 2 procedures, it's never accurate enough to satisfy me without slackening and cleaning out EVERYTHING

if the tools he's getting are £60, it wont be right. the cheap ones are cheese

that's incredibly overdue!!!!! no question at all, get it done or stop driving. I'd recommend Birchdown going by your location

solid lifters add far more to the cost than anything else, and for the smallest gain. Roughly an extra £3k for 5-10bhp. Not worth it IMO, it's not a honda

and push a bit more into the weld rather than pulling

the most from a good FULL build with a lot of attention to detail, without converting to solid lifters (so staying sub 8k rpm) is ~240bhp

Read about someone who was converting a 200sx a couple of years ago. Looks like a LOT of potential

i did say "should". I dont have knock/ignition adaption and i've never had it in any other cars either so i can't give a long term judgement on economy, but i did and do have the best knock limits with tesco 99

well if it's giving knock protection, it should give good economy as that's what governs the ignition timing compensation/adaption. Dont know what the additive they use is, read about it quite a while back

Tescos were selling 99 two years before shell (optimax was 98 RON) They use a different octane increasing additive. Tescos 99 is meant to be one of the best for knock protection, but with the most synthetic additives, so it's "dirty" My car HATES BP fuels, I get detonation like a b*****d from...

there isn't a tensioner on that chain. other engines sometimes use a shim between the pump and the block to adjust it, but i dont know of these for the F4R. Sounds like it's normal really

Infinity is Harmon Kardon's budget brand ;) Well actually JBL is the budget brand, Infinity is middle of the range
