Hi everyone,
In the 6 months I've been boating my old Lister SR2 has been kicking out smoke of a blue-ish white, that doesn't clear no matter how long she's running. I've been told by several engineers that 'it's an old Lister, that's what they do', and while that might be the case, standing in a fuel-y blue cloud anytime I need to run the engine isn't really very fun, and I'd like to do what I can to reduce the smoke and more importantly really understand the issue. I know that white smoke indicates unburnt fuel, and blue indicates that I'm burning oil.
She starts with no problem, and doesn't misfire, but on turning one decompression lever it's clear one of the cylinders is not doing the business. Furthermore, I've noticed when checking the dipstick that the oil level creeps up, suggesting diesel is getting into the oil. I've been going though Richard's troubleshooting guide that i found on here, and have taken the rocker covers off as well as the side plate that houses the injector pumps, hoping to find an obvious leak (no engineer has done these checks). There's a bit of splashing to the bottom right as you look at the exposed crankcase, but it's hard to tell where it's coming from (injector pump?). I checked the banjo bolts, bleed screws but nothing is obviously leaking/loose. I'm really hoping someone will be able to take a look and try to diagnose what's happening.
I realise it could be as simple as a faulty/clogged injector, and this would possibly explain both the compression problem I'm having, and the fuel leak. Any help AT ALL appreciated.
Thanks!
John
