I Need A Fuel System Workshop

[quarkgun]

Hey Guys,

I just got my oil analysis back, I've got serious fuel contamination in the engine oil.

Basically, i need some recommendations on a place in Sydney that can check my injectors (are they leaking?) and other fuel components.

I'm spewing, i put motul chrono in approx 4000 kms ago

Please help!

My fuel setup was done at Autosport, call up and ask for boofhead (some people call him Greg).

He's pretty good with that stuff.

Also, where did you get the oil testing done.....Castrol/Caltex?

I got the analysis done by a mob called e-monitor http://www.e-monitor.com.au/

The lab they used was ALS...

Autosport, is that these guys at Kirrawee? http://www.autosport.net.au/contact.htm

Yep sure is

Thanks for that

whereabouts are you based Marcus? any decent import workshop should be able to get to the bottom of it.

what made you get the oil checked, is there some other problem?

Hey mate,

i'm in the bankstown area. I found this place; http://powertune.com.au/ they're close to me, but seems pretty pricey @ $110ph for diagnosis.

A friend of mine encouraged me to get my oil analysed because my oil (motul 300v) changed colour quite quickly ( i dont do many km's in my car ), plus it developed what seems to be a small hesitation at low revs but high throttle... dunno if that's related or not, but he insisted that i should get the oil analysed good thing too i guess.

Anyway, i dropped the motul oil, and filled up with some cheaper stuff to get me by, hopefully i can get a workshop to find the problem without costing big bucks

[Duncan]

well....prices are heading towards that sort of race at decent workshops, I'm sure you can find cheaper but its not cheaper in the end if they take longer to find the problem. Unique autosports are at seven hills, not exactly next door but probably closer than kirawee.

Interesting results for the oil - did they test for anything other than fuel? I had some checked recently and got good information about the health (or otherwise) of the bearings too.

As well as oil analysis you should get the compression checked, blowby can change the oil colour pretty quickly (as can letting it get too hot of course)

[quarkgun]

True that!

They tested for water and metals as well... attached is the rundown of tests they did. Their analysis was :

"All wear levels appear within acceptable limits for first sample. Silicon level (dirt/sealant material) satisfactory. Water content

acceptable. Fuel dilution at problem level. Viscosity within specified operating range.

Action: Change oil and filter(s) if not already done. Check fuelling system. Resample 250 hrs to monitor and establish wear trend."

Thanks for the tip, i'll get that compression test done as well

+1 for compression test.

excessive bore wear can lead to fuel going past rings washing the bore walls, then into oil.

if not doing yourself, make sure the workshop does dry and wet testing.

good luck with sorcing the problem
