@xulfiqar
I know this is not related to cars but it has an engine so...
I recently got my honda 5kva generator's engine overhauled. I faced an issue of oil reduction and there was blue smoke when i started it in the morning which vanished after 2 minutes. Now after it is overhauled, the smoke problem is still there and i had to top up about 250 ml of oil after 10 hours. It is running on petrol. The mechanic says that the smoke is because of the overhauled engine and it will go away in a week or so..
Is there something wrong??
Thanks in advance..

Bro which plug wires you used and how much they costed you,

brand is sumitomo, they cost me 3.5k and were the last piece at that shop.

Xulfiqar bhai I've sent you a pm, can you please respond?

Would have pasted it here but though that the old thread conversation will remind you the vehicle and current status.

you would have a separate circuit for the lamp in the switch, then you should have switched power coming into the switch and a ground that is swapped around depending on position and two for the motor.

Thanks a lot zulfiqar bhi

Aoa..I recently observed that a a small pipe that is connected to air filter assembly and engine is missing in my civic 2005 and the air filter hole is also sealed .. is there any affect on performance..

You need that pipe asap. Its the breather for the crankcase. Running like this is a sure way to wear out the engine with dust.

[moooniraja]

Ok thanx bro .. i ll soon replace the whole air filter assembly because some mechanic has sealed its pipe hole ...

Its using a bit of oil - it will bed in and somewhat reduce its consumption, but nearly all air cooled genny engines consume oil.

temp in ISB is 0C-45C (MIN AND MAX),so the appropriate SAE rating for cars in Islamabad should be 20w-40??what i fail to understand is why people fancy 0w-40 for Christ'sake this aint arctic on the other hand people use 10w-30 even in summers when the outside temp reaches 45C-imagine the car standing on a signal in direct sun with air con running-i think that is one easy way to eff up an engine
what i want to know is am I doing it right since i use 20w-40 or 20w 50 (cheapest brand available-usually havoline )and i rather spend my money on timely change and OEM filters

The oil viscosity is different for different engines, there is no universal formula that applies to every single engine ever made. - 10W30 oil will have a hot viscosity of approximately 10 cst at 100C. If this is an engine made after 1980s and was built with some respect to workmanship and is not a highly strung one then the manufacturer will have suggested it too.

Using a heavier oil will result in excess fuel consumption and also some startup wear as the oil will not be able to move quick enough.

Another reason to use "fancy shmancy 0W40" oils is due to the strict emmissions requirements which only full synthetics with strong add packs can fulfil. e.g. I can run my mercedes engine on straight 40 API CC diesel oil - it will start and work but the working life of the cats will reduce, the crank may experience fatigue as the engine starts.

In this case we use a "fancy" oil help the engine have a long life and also the emmissions parts to have a long life.

Salam Xulfiqar Bhai.
Issue: Coolant is very low in reservoir bottle. I checked it while refilling Windshield wiper fluid. The engine was cold. Radiator is full since I opened the cap. Car is driven 20,500km.
Should I be worried about a Head-Gasket issue? Is it safe to top it up with a bit of water and then get it properly topped up with Coolant after?
Car is not overheating, even with AC on. Suzuki Swift:)
Thanks!
I read this on Google- Is this correct? The highlighted part.

"Well, I'd use straight tap water to get by for a while but you really need to figure out where the coolant is going. The coolant serves two purposes. Assuming the concentration is correct (50/50% or so), it prevents freezing in cold climates and boil over in warm climates. So you're reducing its ability to protect the engine from either of those conditions by diluting the mixture. The coolant level in the reservoir is lower when the engine is cold than when it's at operating temperature."

All sounds normal.

use mobil1 ATF in place of it - it works sweet. Your required ATF is a HFM ATF (highly friction modified) - like toyota T-IV etc. If you choose a good base stock synthetic multivehicle ATF like Mobil1 - you are good to go.

Dont use the mobil 220 ATF or zic III or caltex DXIII in your gearbox.

i have a carburetor that i want to rebuild on my own, i want to get it running right.........but i also want it shiny :P, i tested sanding a portion of it with 1000 grit and it gained gloss (though i would still be happy if the gloss dulled later on, i just want to flatten the metal so it becomes easy to clean)

i want to freshen up the vacuum pods but want to renew the yellowish coating on them, is there any way i can chrome plate the outside of the carburetor at home and also refresh the coating on the vacuum pods.

any other ideas to make it look good?

[faiz.aslam.121]

Salam again!

Issue: Want to try DIY Throttle Body cleaning.
Will Sea Foam Engine Cleaner be good? Does it damage the engine in anyway? Since you have to add into engine oil as well.
After watching a few videos on YT, I've noticed that they use a Vacuum line to inject it into the engine at the engines own pace, which Vacuum line is the easiest? And, found out that any line that's connected to Brake Booster- A BIG NO

@xulfiqar
Sir I'm planning to sell my cuore after six years. It has done 115k kms on cng with petrol used frequently. On petrol the car barely gave me eleven kmpl.
It had an accident in which it was damaged from the front.
I want your precious advice on what car to buy. It has to be a hatch back. Is toyota etios valco worth waiting for. How is the suzuki swift? In hesitant to buy swift because of paksuzuki's cheap build quality( my cultus came without one of those interior drain plugs:/). I'm also concerned about paint quality and mileage as I would be using only on petrol.

Are those JDMs considerable? I love the paint which comes on these:P
How about getting a suzuki swift JDM as all the parts are available?
Also what are you views on suzuki swift ..
Thanks in advance
