OIL BURNING

[tommy]

Hey Guys

Ok so the 73 Q code 4 speed has done 86,000 miles( original), 2 owners and she's burning oil and blowing nice blue smoke! It runs like a dream, idles perfect,has plenty of power and hasn't done alot of miles in the last ten or so years. But when out for my sunday drives and cruising along at 55 -60 mph take your foot off the throttle and then out comes some good clouds of blue smoke not constant but in puffs. anyway its only done about 150 miles since I got her and the oil level is real low on the dip stick when it was right up on arrival when I checked all the levels. Like I said it runs so sweet but the oil burning has me a bit worried. Any idea's . Rings or valve stem seals ?

Thanks

Tommy:huh:

Valve stem seals, or the drain holes in the heads are stopped up, probably a combination. those are a simple fix without removing the heads.

Like don29163 said, I had the same issue when I bought my car, and it was the Vale stem seals.

Thanks guys

so whats the best method to replace them?

Years ago we did a mates fairlane using a compressor

but now reading about using rope or just going TDC

Just glad i thought to ask about this before I pulled the damn motor out

and went for a rings and bearings job as its been a while since I played lol

I ll definitly check in before i unlock the tool box

thanks again

First thing I would do is a compression/leakdown check on your rings.
