The smoke out the exhaust is fuel smoke, it’s running rich as hell, it’s black smoke. Oil smoke is blue and stinks.

@Woodn509 3 месяца назад

guess it wasn't just me that said not to grease the release bearing......two pet hates I have if someone drives my vehicles, sitting at a junction with the clutch pedal pressed down, as it means that the release bearing is spinning, it's only meant to be pressed to change gear, so will wear out if pressed for a long time, in fact get hot, second pet hate is people sitting without applying the hand brake, but applying foot brakes, on discs it will mean that most of the disc cools, but the bit with the pads applied will not and lead to warping in the long term, grumpy git that I am!!!!

@marcushayesford 3 месяца назад

@tedflowers6347 3 месяца назад

That was fuel smoke coming out of the exhaust, just my opinion but I think you have a bit of bore wash going on there which has damaged the rings. Get to the bottom of the problem now otherwise a replacement engine will go the same way...

Hi mate , could you not go old school and take it to a garage and put emission tester on it and see how rich it’s running ? Maybe coolant sensor is at fault thus sending more fuel causing bore wash as others said need to find the problem now otherwise it’s going to happen with the replacement engine , hope you get to the bottom of the problem mate soon it won’t beat you just a bit of patience, keep up the great work on Heidi ❤

Thanks for the advice mate! 👍 I did have a problem before with the coolant sensor plug coming off the sensor. The readout seemed normal when I plugged the laptop in during this video) but who knows what it was doing when we did the smoke test launch. I can usually notice a serious dip in power when the coolant sensor problem occurs though. 🤔 Defo need to solve this issue before I change the lump.

@danielriddell441 3 месяца назад

Or find a wideband O2 gauge? The price of them has come down loads recently

@stevejoyce2644 3 месяца назад

Definitely overfuelling and bore wash, agree with the others saying this. Black smoke on acceleration a no no. Vvt or cam sensor unlikely to blame, probably the rolling road setup. New rings and hone may be ok, but bearings can also suffer as petrol gets in the oil. (I've a ST170 in an Elan)

@marcushayesford 3 месяца назад

Thanks for the advice mate! 👍 I have full confidence in the tuning when she went on the rollers.

@thughes52 3 месяца назад

The cam sensor m8 controls the timing of the spark via the cam lobe strobe A failing camshaft position sensor begins losing its ability to quickly transfer data. Mismatched fuel delivery and ignition timing, even if off by a few milliseconds, will cause your vehicle to sputter, accelerate poorly, lack power, stall or even shut off.

@marcushayesford 3 месяца назад

Thanks for the advice mate. 👍 Im pretty sure my setup uses the crank sensor to control the spark timing. There are 2 settings for the fuel delivery though (batch and sequential) Batch doesn't need a cam sensor but sequential does. So if the ECU is set to sequential (ill check next time I'm at the garage) then MAYBE the issue Iv been having (potentially) with the cam sensor could also be the cause of messing with the fuelling and causing bore wash etc???? Who knows if any of that os correct but its something to think about. Defo need to solve the issue to avoid ruining the next engine though. Maybe it would be safer to set it up with batch fuelling in future anyway???

@robrs210 3 месяца назад

Sorry but the cam position sensor doesn’t control and spark. It’s there to measure the cam angle for vct control. It will depend on the ecu type if it has closed loop control for the cam advance/retard. If you run closed loom the cam sensor is important. The st170 should run a closed loop vct due the type of control over the cam movement. It’s not the same as other vvt’s which are on/off. The st170 is variable and needs to be used like that to get the best power curve

@user-re3ct9vk7s 3 месяца назад

Looks like it's overfeuling which can cause bore washing with premature wear in the bores

@starfox_wr-45e93 3 месяца назад

The that made me most sceptical about greasing a clutch bearing is: The bearing spins, that grease is surely going to get flung around inside the bell-housing possibly contaminating the friction surfaces? I fear the same thing with melted copper grease around modern braking systems. I'm not using that stuff anymore, better off just keeping the moving parts clean of brake dust and grime, I reckon.

@marcushayesford 3 месяца назад

Very true mate! 👍 the inside of 'Heidi's bellhousing was caked in grease and took ages to clean but the clutch was dry luckily. 👍

@fredjames9867 3 месяца назад

i would get a leak down test before you start pulling it apart . our fast road mini smoked , thought its was knackered . did a leak down was showing really good . got the timing advanced by a specialist and no smoke goes like a rocket ship

@marcushayesford 3 месяца назад

Thanks for the advice mate! 👍 Defo need to solve the issue rather than just throw another lump in.

A leak Down will show its either bottom end or top end . Or it hold fine and then it's something else the mini had been on the rollers and shows that means nothing all this the valve stem seals iol rings . etc . after a 50 quid leak down test . and 40 quid to a race tuner it goes smoke free and going superfast

You should work through it systematically, sensors, wiring and then mechanical, is yours closed loop management? O2 sensor etc. could be bore wash and now glazed walls rings which can be sorted with a hone and rings as long as the bores are still good. But you have to bear in mind the amount of time it spends on the limiter as it could be done.

Does oil pressure affect VVT operation on these engines? Honda's VTEC have that issue IIRC. Low/erratic oil pressure means the VTEC solenoids can't pressurise and engage as they should. Would possibly explain the intermittency you're having, Marcus

@starfox_wr-45e93 3 месяца назад

Edit: from ME's (Motorsport Electronics) site themselves via the "Getting Power with Ford’s ST170 Variable Valve Timing!" page.. Quote: "Simply driving it with a PWM freq. will not work as oil pressure/temp/wear etc will affect the VVT valves flow, and hence cam position."

@marcushayesford 3 месяца назад

Iv defo noticed more recently that 'Esther's oil pressure goes quite low when she's hot (admittedly only when the engine is hot and she's at idle) Maybe the bore wash has thinned the oil enough to make the VVT not work properly which then causes all the other problems?? 🤔

If he had adjusted the linkage or something similar for example and then it started running rough then you’d be onto something, but throttle bodies unlike carbs will usually hold “ tune” indefinitely until something is physically disturbed or something else in the fuel system fails or the stand alone ecu is touched/adjusted etc👍 I’m in no way saying you are defo wrong though as we dunno what may have been touched and when and it could even in an extreme and wild case be a contributing factor to differences between compression in cylinders 👍

Camshaft Crankshaft sensors, as well as measuring the air volume, fuel usage, and engine temp, each sensor has its own optimal range and if one is reading above its maximum permissible range but the rest are within spec the ecu will adjust to bring it in line but because the compression is low the ecu knows that there is something wrong so it adjusts, to compensate ie fuel consumption will increase, obviously it’s more complicated than that but basically the ecu knows that the engine is using more air, fuel, for what revolutions the engine is spinning at so it pumps more fuel in, hence the black smoke which is exasperating the bore wash, a simple rebore and oversized pistons and rings would do the job, or just a new bottom end
