you know what, I've been having a small issue with the 2.2 puma engine in my peugeot boxer for years now. the engine has been running fine all that time. it's a campervan which I take for 2 long trips a year, it does some 6-7k miles annually. for all this years I've been trying to find the reason why the engine chucks bluish smoke when revved up to 2.5k rpm but only when stationary and not driven. even if it starts getting to temperature when I rev it it'll start throwing the smoke. when I drive off immediately, no smoke when driving, it gets to running temperature, I stop rev the hell out of it and no smoke (a bit black smoke maybe). I replaced injectors, EGR (which I blanked later), glow plugs, turbo, cleaned the inlet, new timing, filters obviously, suction control valve, put a oil catch tank on the hose from crank breather to inlet. The van always started no problem, always drove perfectly, no misfires. when I'm high up in Alps it would trow some black smoke when I accelerate from let's say 1.5k revs before the turbo kicks in. Now regarding your video. After my last trip to Alps a month ago the van developed slight ticking/tapping noise as if it was from the valves or injectors. It's mostly heard when cold and almost dissapears when warm. I decided I'd do a compression test which shows more or less 25-26 bars on all cylinders. But then I decided while I was at it, I'd do a leak down test. I removed the rocker carrier because I want to replace the valve stem seals (it's the last cause of the smoke I can think of) and so that I dont have to worry about the stroke it's in when measuring (all valves closed all the time). And to my surprise cylinder 3 and 4 have obvious valve leaks! Almost as pronounced as those in your video! I sprayed some oven cleaner in the intlet port while I was replacing vale stem seals on cylinder 4 and moved the valve up and down a bit spun it a little while pulling agaist the seat. And boom, no more leak from the inlet valve, but a leak from the exhaust one 🙄I'm wondering what could that be? Carbon buildup? why does the engine have such good compression though. Now I'm on the fence here. Shall I leave it the way it is or is it better to take the head off and get it redone. Do you remember what was the problem in the one on the video? I'm reluctant on taking the head off as so far most of my fixes didn't actually fix the issue I was trying to solve 😂Cheers!
You're obviously a man who knows what he's doing! Brilliant to watch!
