I have the basic 16 g setup 550's safc 3 inch exhaust 3gm maf car was tuned by extreme I baby the car all thetime I'm not that hard on it jus the other day I was going to gett coffee abd I started hearibg a knock it was incomsistant at first then I tried startingit today and its become consistant with rpm rise and fall . you can feel it hitting smething but I can't tel if its coming from the head or the block either way . the car idels fine and goes fine right up untill you hit boost then it starts to feel like the boost holding the car back instead . I just did a head gasket change and everything looked fine .

the knoc def sounds like its coming more from the block


this is a 95 tsi awd with the 7 bolt
please help me shed some light on this thanks

That sounds a lot like rod knock, unfortunately. Have you had any oiling problems with the engine lately?

 

[TSIfreek]

The headgasket change you did my have put debis in the oiling system cleaning the deck wiping out the bearings I see it all the time. Internitent knock is a rod.

To be sure it's rod knock start the motor and rev it to the point at which the sound starts. Pull and replace one plug wire at a time and see if the sound disappears. If it does, it's likely rod knock since the load is being taken off of that particular piston. Keep in mind that a bad case of rod knock will come on at idle.

Post back and let us know what you find.

Has the oil presure fluctuated any? Have you removed the balance shafts? My guess is that the rear bs bearing has shit the bed.

ill be honest im still a little new to everything , i did all my own work and my own head gasket but i am learning ... the knock is very apearent right at idel , i will go and try to remove the plugs if i take the plugs out wont they gap to me ..and wont that hurt like helll......

 

[hondamunchergsx]

one more question , would rod knock be the reason that i cant hit boost , im just asking here cause i dont know ...and i just spent a crap load on this car and i want it to be on the road ...

 

[Quasimondo]

Pull the plug wire from the coilpack when the engine is shut down, not while it is running. If you do have rod knock, you have bigger things to worry about other than your engine not being able to build boost.

Definitely rod knock. Had this happen to several cars. Time for a rebuild.

Your not able to build boost because you have 43 counts of knock all the time with out timing advance you wont build boost.

Pull the oil pan then you will know if it is a rod or balance shaft. Here is what I found in mine after it started knocking...

Not the greatest quality and it was really dark...attempted to hold the flash light and recored but hey it lets you hear the sound Its definately time to get the pan off and see whats going on

 

[Quasimondo]

That sounds very much like rod knock. Those who've had it can never forget it.

 

[90turbotsi]

agreed

 

[andymoraitis]

That sounds very much like rod knock. Those who've had it can never forget it.

Hearing that brings back too many awful memories or needing a bottom end rebuild...

 

[Spoolin4Ever]

Yeah I do recall hearing that a few K$ ago...ye old 1G 7bolt itwas...132K miles on 'er.

I see a 6 bolt in your future. You are officially a DSM'r now. Especially once the 6 bolt is installed.

Don't worry, like the Phoenix from the ashes, the mighty Eagle shall rise again. (or eclipse whatever hehe)
