Recent engine rebuild ( Loudish Metalic Ticking noise)

[grahams81]

Dan, like you say mate can't do any harm doing another compression test, but it soundn't make much diffence if the engine is hot or cold.
Would be interesting to see if there is any difference though mate, might help you with the fault finding.

From what you say about the vvt it sounds very timing related to me, pop the rocker cover gasket and check the cam chain there should be 16 rollers countable on the top run of the chain (starting from and including the one above the arrow on the bearing caps and including the last one above the arrow)

Heres a linky incase i never explained it well - http://www.seatcupra.net/forums/showthread.php?t=240036

Let us all know how you get on matey.

Thanks graham il have a look tomorrow I've done around 100milea in it and once the water gets to 90c on the dash its kinda sorts its self out.
.
But today I thought id try full boost in 2nd and the tcs kicked in and t popped really loud then it ran lumpy as **** and spluttering so pulled over and a quick check so couldn't see anything then unplugged the msf to get home now...

I've plugged it back in but the Tcs light is on all the time now along with the eml light...

How did it run with Maf unplugged?

 

[cupra_r_ick]

My tc and eml came on when I was over boosting like mad and going into limp mode, so doesn't necessarily mean your mafs gone I was getting maf faults, saying it was over reading, crappy take turbos fault, can't see this being your prob though as I doubt it would cause misfires

 

[cupra_r_ick]

Haven't read all the posts, but have you done a cylinder leakage test ? And did you do a compression test dry, and wet ?

 

[RS6]

you need it checked over any local tuning places have a look for you something not right somewhere

Dan, my LC was doing the lumpy starting and missfiring and it turned out to be the pre cat lambder sensor just thought i woiuld throw that in the mix.

 

[DaNnY_LaD]

Ive just scanned it and got these codes...anyone now what they are?

17939
16684
16688
17608
16717
16486

My Maf is well and truely ****ed thought...TCS is on all the time...

 

[dtmwelburn]

They not on the list on rosstech website mate?

17939 P1531 Camshaft Control Circuit open

16684 P0300 Random/Multiple Cylinder Misfire Detected

16688 P0304 Cyl.4 Misfire Detected

16717 P0333 Knock Sensor 2 Circ High Input

17608 - Boost Pressure Control Valve (N249): Mechanical Malfunction

16486- MAF low signal

17939 P1531 Camshaft Control Circuit open

Is fault from being run with the VVT sensor unplugged

16684 P0300 Random/Multiple Cylinder Misfire Detected

Still same issues with the miss fire

16688 P0304 Cyl.4 Misfire Detected

Still same issues with the miss fire

16717 P0333 Knock Sensor 2 Circ High Input

Unsure, maybe a faulty sensor or because the miss fire issue

17608 - Boost Pressure Control Valve (N249): Mechanical Malfunction

Been bypassed but still plugged in

16486- MAF low signal

Been unplugged and drove home. so will log a fault till it is cleared traction light will come on with this fault aswell.

 

[DaNnY_LaD]

This is and the cyl 4 miss fire are the ones im always getting

16717/P0333/000819 - Knock Sensor 2 (G66): Signal too High
Possible Symptoms
Engine Damage
Possible Causes
Knock Sensor 2 (G66) improperly torqued
Possible Solutions
Torque Knock Sensor 2 (G66) to specifications
Check Knock Sensor 2 (G66) and Knock Control

I also forgot to mention yesterday when it pop and spluttered i had no boost soon after and im getting a drone noise from the exhaust if i try and plant it...Car sets off fine and idles fine.....

also do i have to time the engine up to check the timing chain.,

 

[Phillc]

also do i have to time the engine up to check the timing chain.,

When you time it all up there should be 16 rollers between the cam timing marks with no1 at tdc.

 

[cupra_r_ick]

and the arrows on the bearing caps pointing to the markings on the cams.....

 

[Phillc]

Errr Yeah like i said.........When you time it all up there should be 16 rollers between the cam timing marks with no1 at tdc.

 

[cupra_r_ick]

behave

 

[DaNnY_LaD]

So I time the engine up with a 19mm socket on the crank and the notch on the top of the cam sprocket pointing upwards

 

[Phillc]

behave

.................................Sorry.

Yes Dan, line the mark on the pully with the mark on the pully cover and the cam pully mark with the mark on the cam cover then look at the cam timing arrows and make sure they line up with the marks on the bearing caps, then count the rollers beteen the marking and there should be 16.

 

[DaNnY_LaD]

ive timed it up and it looks like 16rollers like you say..
