Sounds like it's lunched an apex seal. do a compression test to check.

Ford laser 99 no power


Hi there.
well when you throttle up to about 2000rpm do you get blue smoke coming out the exhaust.When driving on flat road will it power up as normal with out missing or getting hot.
what colour was the old spark plugs were they black or light brown.
When you start engine and run for 3 minutes then let it idle and remove oil filler cap do you get smoke coming out.
Number 1 if yes then engine is lacking power due to piston rings worn answer rebuild engine.
Number2 spark plugs brown [good] if black soot as num1.
Number 3 if you get black smoke or blue ,then the engine is lacking compression could be your problem as num1

Sometimes not always - puff of smoke when starting ( light colour) followed by lumpy tickover and noisey clacky sound from engine - all becomes ok when warm


I suspect smoke is just condensation in exhaust from suiting overnight. The other descriptions sound like it needs an oil change (noisy clacky) and lumpy starting sounds like dirty battery cables - clean them top and bottom. ??- When was last "healthy" tune up? Plugs, wires, all fluids & filters? I'd start there.

Engine light came on wit lack of power spluttering and wgite smoke from exhaust


Dear Sir,
As you said engine light is on and misfire with white smoke, it clearly symptom of poor ignition spark may cause of any wire got disconnected or spark plug faulty.
white smoke comes only in case no spark at spark plug and un burn fuel throwing from silencer. check wire and spark plug if any issue let me know. thanks.

Large amount of white smoke on first start of the day


Have you had the injector recall check carried out? There is a problem with these injectors and this produces the symptoms you are describing. I suggest that you contact Isuzu direct for help. They have been very helpful in the case of my trooper

Black smoke from exhaust


This is almost certainly a split hose - mine was the large hose coming out of the bottom of the EGR valve.

Speaking to a parts guy at my local Jaguar dealer, he said that the new part is uprated as Jaguar are aware that this is a problem.

The split allows more air in and results in the ECU changing the mixture and over fuelling - Black smoke is an indication of un-burnt Diesel. As well as the black smoke you may also notice a whistle/whine or sucking noise when you accelerate and a lack of power / lumpiness at around 2000rpm.

Hope that helps!

Black smoke from exhuast


black smoke from exhaust means a rich oil/fuel ratio, sometimes it causes by a clogged air filter or a problem on fuel injection system.
