Blowby

[Bushwagon]

Hi everyone.
I own a diesel s124 wagon with 650.000kms
I've done some serious work on it for the last 2 years, think I've had every single problem you could think of, this was a very tired car and it has come a long way ever since.
Recently I noticed something new..... I have some blowby, and this has really upset me as I have put some ridiculous man hours on this project so far.
Now I've read countless threads over different forums over this topic but I'm still confused.
I'll discribe my symptoms the best I can.
Upon start up with a cold engine i get blue smoke not massively but some, the injectors are new monarks.
With the engine cold if I open the oil filler cap the pressure rattles the cap, doesn't blow it across the yard but rattles.
So far I had to replace all rubber bushings hoses etc as it was all pretty gone. I wonder before I assume the worst "rings" if this excess blowby could be caused by the valve stem seals? As they are made out of rubber too? This car had spent a great deal of time parked before I purchased it. Maybe that could help with their deterioration.
Any ideas or related experiences are welcome.
Many thanks

Hi,
I am not familiar with your engine, however, do you have an item similar to a PCV valve --Positive Crankcase Ventilation, that may be blocked caused a build up of excessive pressure inside the engine. ?

Hi Steve
Thanks for your reply.
I do have one it's all clear there, the engine it's a 602 I believe 250d no turbo.
All oils and filters are changed religiously, this syptoms started almost Imediately.
My dad got one same engine with one milion and 300kms never had ring problems, personally I've never seen one doing this at this age... but there's always a first I guess....

Could well be valve stem seals. Generally if it was rings, it would give blue smoke form the exhaust all the time, not just on start-up.

That's my theory but then I never had this before, and there's not so much info out there on these engines regarding this issue.
Also have a ticking noise that seems to come from the lifters, goes away on higher revs not always constant comes and goes as it pleases I wonder if that is related or just another issue.
Anyone here as ever done the valve stem seals on these diesel engine's with the head on? Rope method?

If you scrap it and buy a Kia you will save so much money in the long term
