Re: Low Compression bent rod? WPS

Well this didn’t go quite to plan although we can confirm that it was definitely no.6 and it was most definitely a problem with the rod the only trouble is it’s now on the outside of the engine and we haven’t started stripping it yet :shock: The customer kept changing his mind as to what was going t...

Today's subject is a 2005 Scania P380 DC11 Pde 32 tonne tipper, it come in with a fairly serious misfire and was breathing heavily and with a knock under load apart from the obvious breathing and oil staining around the breather pipe the visual inspection provided no clues and fluid levels were all ...

Re: Peugeot 308cc RHF Engine Will not start

I maybe way off as I know nothing about the specific system you are working with but I went out to a renault truck as a call out yesterday and that had a similar issue where it would run on brake cleaner but wouldn't start otherwise and it logged no faults, The dealer breakdown service had been out ...

Re: Low Compression bent rod? WPS

Well it seems we may still get an answer on this as I have been asked to continue to try and find the cause first so I am gonna get it running again and warm it up which will give me the chance to give it a thorough wash and hopefully see if anything leaks under pressure when its hot and then I will...

Re: Low Compression bent rod? WPS

Hi Steve, thanks for taking the time to put that together, I did try a similar thing last night but with nowhere near the detail of yours and they were both the same colour which didn't help but I guess that comes with practice. I got the chance to question the driver myself today and it turns out o...

Re: Low Compression bent rod? WPS

I decided at this point I needed to access and remove injector 6 and upon removing the rocker cover a visual inspection of the cam/valve gear revealed nothing and there was still no signs of oil contamination. After confirming the compression was low with a manual gauge I done an in cylinder with th...

Re: Low Compression bent rod? WPS

Due to the even pulses in the fuel rail pressure I was happy enough the injectors weren't the cause of the hydro-lock added to it being the rear most cylinder and with the engine angled slightly backwards points me to something entering via the intake. Normally I would suspect the Egr cooler dumping...

Re: Low Compression bent rod? WPS

The next step was to run the engine to show the Cam signal against an injector current to ID the offending cylinder, I used cylinder 2 as it was the easiest to get an amp clamp round at the ecu because the injectors are fitted under the rocker cover which is a mission to get off due to the air clean...

Low Compression bent rod? WPS

Having recently purchased a WPS500 I like to use it where possible even when I have a fair idea whats wrong to aid learning whats good and bad for when I have no idea. So I thought I'd share what I'd taken in case it may help others and also if I may be missing something which is highly likely being...
