First, you must determine what is causing the oil usage. Heavy blue smoke come from the exhaust when you back off the throttle then get on it again? That is probably valve seals. Does it smoke when you full throttle it? That is probably piston rings. There is no cheap way to repair an engine.. Valve seals are much cheaper than rings to repair. You may want to try putting a can of STP in the oil and see if that helps. Beware of the magic formulas that claim they can fix anything.How do I stop my truck from burning oil?
No way to do it proper. If you add thicker oil it may slow it down, but that is not good for engine
If the oil is coming out the tailpipe as smoke, you need new piston rings. If it is coming out of the vents in the valve covers, you need new valve guides. There is no easy fix. The best thing to do would be to completely rebuild your engine, or replace it with a crate engine. I would go with a factory new crate engine, myself. For about the same price, you get a new engine that should last twice as long as a rebuilt one.
I would like to make a million dollars working at home 5 hours a week! If you motor is buring oil, it needs a mechanic. There are no good ';cheap'; soultions that will work. You may need piston rings, valves, etc. Learn to deal with it or get it repaired properly.
The only real cheapest solution to your problem is to get an overhaul done to the motor. Now might i remind you that an overhaul is not a rebuild there is a big difference between the two. An overhaul is just taking the pistons out and having the cylinders rehoned and new rings put on the existing pistons. Then moreless a gasket and seal replacement from that point on with the top end. A rebuild is baically that a rebuild. The entire engine is gone thru and redone. In my opinion if your gonna keep the truck longterm, i would invest in a rebuild but if you dont plan on keeping it for too much linger but would like to realisticly resolve the oil burning problem then a overhaul is just what you need. The overhaul is a bit more cheaper to perform than the rebuild but if youre gonna have to remove the entire engine to do the job like it requires you might as well go the whole nine yards. just an opinion. Good luck.
INsure it and roll it off a cliff.
You have a god truck Rob..if the body is in good shape. But, if the engine is burning alot of oil then the rings are probably worn. Your best bet if you want a permanent long term fix would be to purchase a short block from a reputable auto parts store or machine shop and do the swap thingy. You will otherwise end up waisting alot of money before finding out that you are back at square one. Good Luck guy....
No easy solution without rebuilding the engine
If it has a 307, they were notorious for the valve seals going bad. This causes oil to leak past the valves into the combustion chamber and burn. Rebuilding or replacing the heads is the only solution. As this engine is 35 years old, it most likely needs a rebuild. Band-aid fixes won't work.
If you are serious about keeping your truck, you could consider installing a new GM Performance Parts GoodWrench 350. This engine is made from all new parts, not rebuilt. It will bolt right in place of your old V8. It produces about 260 horsepower, which will most likely give you more power than you have now.
It will cost you about $1500 + shipping. Search for item number NAL-10067353
The Summit Racing website has lots of choices for replacement engines.
You are going to face up to the fact that your 35 year truck has a tired engine and in need of an overhaul. In particular, the rings and valves need attention.
There is no magic wand to repair a worn out engine. You can do much of the work yourself if you have the tools and the mechanical ability. Most of the cost in repairing an engine are labor charges. For example a set of rings runs about 100.00 and the labor to install them about 1,500.00. If I were you, I would explore my options. I rebuilt my first motor in a friends garage with his father as a reference whenever I got stuck. We did an ';Okie'; overhaul and replaced the rings, rod bearings and valve seals in one weekend for about 200.00. That was a few years ago and the truck is still running fine. This is no guarantee that when you disassemble yours you will not find additional needed repairs, but my engine ran great, just fouled plugs with oil and burned a quart every 300 miles.
Most reason this oil burning happens because the valve guides have gone bad.Its common on older higher mileage Chevy engines.Most of those old Chevy engines can run forever with this issue just fine without any problems as long as you remember to check and add oil.The valve guides help to guide the oil in the cylinders where the combustion takes place and helps to keep the oil more at the cylinder walls where the piston rings run it up and down the cylinder walls for protection.Not a problem unless run too low.
What you need to do is have what mechanics call ';a valve job'; done on the truck.It will cost you around $450.00 to $600.00 to have this done.Not too bad if you plan on keeping the truck and don't want to risk burning it out of oil and frying the engine cause you forgot to add oil.
the rings are going out rings around the cylinder head or pistion
