Blue smoke on start up

I have 2018 turbo rzr with 1000 km just noticed now that it smokes blue on start up. Is this something I should be worried about or anyone know what's causing this issue

Re: Blue smoke on start up

Blue smoke at start up in cars is oil typically. I am brand new to these things (RZRs) so I would not hazard a guess as to what it might be.

Re: Blue smoke on start up

Turbodan.....I would be very concerned !! ... First make sure the simple stuff is checked ...

1...Double check oil level (assuming you are using a good/ correct type oil)
2...check spark plugs and depending on looks change check gap should be .020 inch or close
3...check air filter and intake behind filter for dust
4...if you dont see anything wrong than go to the dealer soon and start compression test ect ..

Also do you have mods ...flash ...or other engine ....ECU mods ?

Sounds like valve seals. Almost every single RZR I have owned has had issues with valve guides and or valve seals. Polaris uses junk steel china valves and junk china iron valve guides. Actually just did low compression pistons in my 2018 rs1 for a turbo build. When I inspected the head while it was off too my surprise at 2100 miles the intake valve seals and 2 exhaust had already shit the bed. You could physically see the oil on top of the valves on 6 of the 8 ports. I also found the intake valves needed adjusted already at 2100 miles. My 16 xpt also had valve seals issues but I never bothered to fix it and I sold it. It would only blue smoke for 2 seconds or so if it sat 3 days or more. My 900xp ate the valve guides, valve seals and Intake valves in 2200 miles. I would be willing to bet it's the start of the intake valve seals.

Should I be concerned and get it fixed right away or just drive it

Re: Blue smoke on start up

When an engine smokes upon startup 99% of the time the valve seals are bad.

Rzr_joe.. is this a big job to replace the seals?
Will it hurt the engine if it's driven like that?

If it's just the seals it's not that big a job. It can be done without removing the engine. It does require a few specialized tools and mechanical knowledge.

If it only does it on startup and it stops quickly it's not a huge issue but it will need to be addressed eventually. This is especially true on a forced induction engine. When the oil contaminants gets into the cylinder it can cause detonation, excessive blow-by, plug fouling, etc..

Keep an eye on it and if it gets worse, starts using a lot of oil, or starts running rough you'll need to address it.

Thanks for input I'm going to try and get in the soon as possible
The machine still has warranty just have to convince the mechanics there's a issue

Valve seals on the xp900, xp1000,and xpt are a big deal to replace. You cannot get a external spring compressor down onto the valve spring due to the bore for the cam buckets are too small. You would need to pull the head to replace the valve seals. If it's under warranty you need to push them big time that it's using oil and smoking. The parts are relatively cheap but the labor is very big to do them if you have to pay to have them done. Chances are you may even have some valve guides on the loose side as well.

Re: Blue smoke on start up

Did not know you couldn't get a spring compressor in there, that sucks.

I think it would be impossible to do them without pulling the head. Here is a xpt head I have on the shelf. They are reassessed into the head casting and only have 4mm or so around the spring
