300,000kms worth of cr*p in plenum and TB * Photo Heavy*

Not to mention the quicker times you'll get cuz of the weight reduction

haha you know it! :dance:

 

[imnothereanymore]

wow thats really surprising to see that much gunk
i cleaned t/b ages ago and i thought that was heaps better for car after now i might do this too soon

 

[Philthy]

Wow thats a lot of crap! Maybe this weekend I'll rip into mine and see what I can get off it

Holly cr@p!! That is alot of sludge on the TB butterfly.

 

[delcowizzid]

looks like burnt on oil from the EGR valve cooking it on the throttle butterfly maybe the EGR valve is a little knaffed and not closing or the cars not heating fast enough or something ive never seen one like that ever

nah that looks pretty average for A 300,000 km old ecotec to me... work on the things for a living and believe it or not ive seen worse than that! not around the throttle body but around the 5 and 6 intake runners especially.... crappy oil and long service intervals are the main contributors to that carbon buildup

 

[HoldenOnn]

Would you like sauce with that

I don't doubt what you are saying but don't get how it is crappy oil that would do it. It used to be a monthly thing on my two stroke bike, however in a four stroke I would have thought crappy fuel and lack of servicing?

Maybe I am believing the advertising for BP ultimate too much

Nothing to do with the oil, its all about how these engines breath etc. Plays an important role in the longevity of internal seals as well. Check the PCV valve for this. EGR valve worth checking too. I hope you didnt wash all the gunk down the intake runners ?

What is the best way to take the cover off?
Do you have to disconnect anything like the battery or?

and can a novice attempt this?

Thanks
