I have 2 low mileage pintos (25K and 85K miles) with the 2.0L in them, they both sat inside out of the weather for years, after getting both running they both started smoking, seems to be worse at idle, but they do smoke going down the road, I pulled the valve cover and the valve stem seals are still intacked and appear ok, PCV is working correctly, I'm starting to think it may have something to do with the Chrome rings and sitting in one place in the cylinder for a long time. Idea's???
Where the motors fogged before they where stored ?If not than the rings might be bad.... What I mean by fogging is an oil that is shot in to the carb when the engine is running to coat the engine internals before long term storage....If it's not done your rings can become dry and fail. Thus the smoke.What are the oil pressure readings ? Are the spark plugs black ?
who knows how the prior owner stored them, all I know is they both have done the exact same thing, I pulled apart the 2.0L that has 24K miles, I could find nothing wrong with the bottom end, even still has nice hone marks in the cylinders, I did have a couple valve seals that had moved up the valve stem, the next one i think I'll just try and rebuild the top end and see what happens,
Hope it all turns out okay!
Are they automatics or 4 spds? If automatics check the modulator valves. They may have dried out from storage. If the diaphrams crack the engine will zoop transmission fluid thru them. Check the vacuum line from the modulator to the engine and look for signs of the hose being wet inside. Just a thought.
1 is an auto the other is a manual, i can find no sign of tranny fluid in the vacuum line
Do the 2.0s require valve adjustments like the 1.6? I don't know if that would be an issue, but you never know.
When I first got my 73 squire it was at or near 52k miles I ended up having to replace valve guide seals,cam and lifters,due to flat cam and sticking lifters because of the car sat for so long at the original owners house. This was the first thing I fixed then it was on to tje carb.
Lemme know if you end up changing the valve stem seals. I haven't found a spring compressor at any of the auto parts stores that is small enough to get the rear and front springs out.
Dave my spring compressor works fine if the head is off, If your head is off let me know and we can do the valve seals no problem..
Yeah, I have the head in storage, everything is on it. The camshaft is even secured. I hit it with wd-40 and applied some oil to the lobes to keep the rust away.
I'll give you a call when I am done doing my 78's suspension and steering rack.
My parents bought me a 12 ton shop press for my b-day, so if you need any of that sort of work done lemme know! :)
