RVR HSG Head Rebuild - Now vibrating violently/no power

Hey,

Sooo I had my head rebuilt and picked up the car today. It was just as the mechanic was closing. On idle the whole car vibrates really bad and it stays like that all the way up to 3000rpm, then smooths out a bit, but still no where near as smooth as it was when i took it in to have the work done.
I am taking the car back tomorrow morning, however do you guys have any idea what this is or could be?

I was thinking maybe the timing?

Cheers, Mike

Balance shaft timing, cam timing.

Does anyone know what the cam timing it meant to be at all? The car seems really low on power as well

Balance shaft is 180º out.
100%

Remove the balance shaft plug on the rear side of the cylinder block and insert a Phillips screwdriver {shank diameter 8 mm (.32 in.)} through the hole. The balance shaft is in the correct position if the screwdriver can be inserted at least 60 mm (2.4 in.). If the inserted depth is less than this only 20-25 mm (.8-1.0 in.), the oil pump sprocket must be rotated one full turn and timing marks realigned. Recheck the balance shaft position using the screwdriver to ensure that it can be inserted 60 mm (2.4 in.) or more. Keep the screwdriver inserted until timing belt installation is complete (Figure 13).NOTE that there is an easier way to do this. Simply rotate the mark on the oil pump sprocket until it is pointing straight up, and let it go. If the sprocket rotates towards (counterclockwise) the timing mark on the engine, the oil pump sprocket is aligned correctly. If it rotates away (clockwise) from the mark, spin the sprocket a full turn and test again, and it should properly rotate towards the mark now. Now line the mark on the sprocket back up with the mark on the engine. This avoids having to remove the rear access bolt entirely.Caution:MAKE SURE THE BALANCE SHAFT IS PROPERLY POSITIONED. It is possible for the oil pump sprocket timing marks to be properly aligned, and have the balance shaft out of phase. This could result in a SEVERE engine vibration.

An easier way is to rotate the balance shaft (oil pump one) and see if it rests in the timed position.


The screwdriver thing will work, but I find it easier to just turn it slowly and find where it wants to rest.

EDIT: Sorry Jamo, just read your post properly, you said it perfectly :thumbsup:

Don't tell your missus, she'll end up sitting on the bonnet instead of the washing machine LOL

Thanks so much guys! I can almost guarantee this is what it is, they might have just lined it up.
I'm still taking it back there to get them to have a look. Shouldn't take them too long should it?


Cheers, Mike

Its a bit of ******* around. The timing belts and all the covers have to come off. So might take a couple of hours depending how good they are...going off there last efforts they arent exactly 100% competent.

Yea thats true mate! I have been without the car for 9 days already
Hopefully get it back tomorrow arvo haha!!

Would this be causing the loss in power at all? Or is that more likely cam timing?

It has been 48 days since I drove mine

Thats crap man! You take your car somewhere and expect them to sort it and it's coming back to you worse than when you gave it to them.... Call Gavin, he'll sort you out.

I don't think it should. They must have done something else wrong?

Yea man, I realllllyy hope I get it back tomorrow, then i'll wind the boost up a bit!!

Tell them to make sure not to damage crank angle sensor once they do it. It may cause you headache.

God dammit, anything that can go wrong with this will, I can see it happening!
