seen the exhaust no oil trace but i think I did react fast enough to avoid any potential damage to oil seals - got rid off about 600ml excess filled the problem looks 100% sorted but i keep an eye on the exhaust when i start in morning to see if any smoke is coming out. have to keep the babe in good condition as my registration is next month. thanks anyways all of you for all help extended. much appreciated.

Finally, cleared the doubt of our heads, bro.

Well, then i've heard that in UAE, the cars are checked annually if they're road worthy.So, thats what u meant.

get your carburetter tuning checked it the cause of the black smoke and also check your spark plugs.

Was checking the effects of excess engine oil levels ..

Had two engine oil changes in about 2 weeks for both my vehicles.

1. Sumo:
recommended quantity: 7.7 litres
Oil level about 5-7mm above upper limit on dipstick.

2. Indigo Marina:
recommended quantity : 5.5 litres.
I got the TASC to fill in only 5 litres. The oil level is just short of the upper limit on dipstick. So 5 litres is actually enough.

Dont understand where is the mistake. TASC emphatically says that they are not responsible if anything happens due to lesser engine oil. But they fill & bill the recommended qty, and this is actually in excess. Going to ask them if they will take the responsibility in this case.

Oil filter was changed in both cases

Has anybody else checked this - recommended qty vs level ?

OT: was trying to add bardahl to the crank case when I got into checking the levels. I had to have some oil drained out from the Sumo before adding more Bardahl.

My old Amby is smoking out black if i throttle in all gear shifts .....

Visible black smoke in normal speeds ....

Emits huge black smoke when i speed up above 50kmph in top gear , above 35kmph in 3rd gear , above 20kmph in 2nd gear , above 10kmph in 1st gear....

Oil Level is fine .....
Head gasket is fine (No Overheating problem) ....
Clean Engine start without using heater .....
Checked the Fuel Injection pump .....

Please give me some ideas to make smoke invisible .....

is it running rich? Did you check if the air-fuel ratio?

is it a diesel / petrol amby?

EDIT: ok it is a diesel (heater)

Diesel amby ...
How to check air-fuel ratio ??

I'm glad you've identified the problems and solved them! I have only just seen the thread!

Overfilling of oil is as dangerous as underfilling.

You will generate more drag on the crank if the webbings are hitting the oilin the sump the more oil the worse the damage and a serious overfill even allow pistons to hit the oil resulting in danaged rods. There will also be potential damage to oil seals and decreased performance, increased petrol consumption.

People often just fill them a 'little bit more' for safety in the misguided belief that it better to have a bit too much in. This is a big mistake! Manufacturers didn't put a maximum level on the dipstick just to spnd money. Never overfill over the maximum level with the engine switched off and stationary on level ground and cold!

I remember my uncle telling me one day when he worked for Volvo Penta as a senior technitian that he was sent to tune one of their powerboats that wasn't making the speeds they wanted in racing. They had a team of experienced technicians there that just couldn't get the last few knots out of the machine that they required. When he went to look at the engine he discovered a slight overfilling of oil that once removed ment they hit and also exceeded their target speed.

Its attention to detail that make the difference between good engine performance and poor performance.

i thought it is a Petrol amby and that is why i mentioned A/F ratio.

how do the PUC certificate read?

Vasanthan · 9th August 2010, 22:22

have checked the fuel that returns to tank ..... Not mixed with coolant or oil
have checked the coolant that returns to radiator tank .... Not mixed with fuel

u have any idea other than these ?? regarding exhaust pipe and mufflers ??
