Try setting the cams to the correct clearance. Maybe a worn cam.

Have 1965 vw beetle and put new engine in it and change everything and can not get it to run

New distributor? new points and condensor? Wires correct? Valve clearance set when cold? The valves need adjustment when new and every 500 miles per manufacturers specifications. New coil? All these are factors.

I would unplug the parking brake switch and see if the light goes out. The erratic idle indicates a possible vacuum leak, check carefully around the throttle body mounting. Since it sat for a long time the throttle body gasket may be leaking. Check the intake manifold for tightness too. You probably replaced the PCV valve already. Leaking head gasket, may want to do a compression test. I did some checking and unfortunately your mileage may not be that far off, I got a wide range of fuel mileage ratings from 11mpg to 14mpg. That being said, a malfunctioning emissions system or restricted exhaust could cause excessive fuel consumption. Any chance a rat climbed in your tail pipe and built a nest? Ha Ha Ha. You haven't mentioned any check engine lights being on, still there could be an emissions system problem.

Is valve adjustment a part of normal maitenance on Suzuki Esteem

When you hear some tapping, that's why you need -valve adjustments. At 137,000miles you probably need more than that to continue your trouble-free drives.

My valves are ticking on my 97 doge 2500 pick up it has the 360 magnum can i adjust them or not .....

Ticking sound is normal from a health diesel engine is normal.

Diesel engine that does a lot of towing or carry large payload can use a head adjustment every 2 years or 24,000 miles.

I would keep tabs on the valve cover for oil leak.

Take it in the shop when the valve cover start to leak.

Do the valve adjustment,the valve cover and oil change at the same time.

Shell ROTELLA T Multigrade SAE 15W-40 is my prefer motor oil.

How many miles have you heard of being on a 3.0 liter eng? the reason I am asking is checking the end play on motor has very little and it seems to be a tight little motor. when i worked at chrysler seemed...

I have a Mitsubishi Montero with 280K on it with the 3.0 liter (only issue was valve guides, I had the heads rebuilt) My first Montero I had 248K on it before I sold it, ran great. My son has a Dodge Stealth with the 3.0 V6 in it. Again I removed the heads because of valve guides but after 120K miles the cylinders STILL had honing marks on them. They can be tough to service but they're a great engine, in my view.
Best regards,

2001 HD 2500 6 Litre poor starting

if it`s burning some oil it probably needs new valve seats in the heads and it probably isnt piston slap noise but the rockers getting looser. If you have the heads redone make sure the push rods are cleaned and not damaged I`m sorry to say but that slap going away will only be temperary as it continues to where on the valve seats it will start again you did the right thing though by switching motor oil if you do make these repairs you might want to add something like prolong or slick 50 well hope this helped
