How many washers is too many washers

Just did my front turbo. Shimmed it with 2 washers on each bolt.

Did my vac test and barely closes any sooner. I can still trigger 30ff. I think it’s helped slightly but barely.

So how many washers is too many on these bolts?

Does anyone know the thread pitch and bolt size? Maybe i can get longer ones?

My rear turbo is adjusted to close at 6hg and it does and doesn’t seem as bad as the front.

If you put two No. 8 washers on each bolt, and still are getting 30ff codes, then either you have a leak or the wastegate actuator is toast. If the wastegate actuator is toast, the turbo itself is probably gone too.

How much boost are you able to get?

How old are your boost solenoids?

I think i am actually retarded. All i did was take my bolts out, put washers over them then screw them back in. Damn it’s a long day.

I didn’t shim it at all don’t know what i was thinking.

So i have wastegate > washer > washer > bolt

Instead of

Washer > washer > wastegate > bolt

I just redid this job. I got cocky and figured it would take like 30 mins. Took me like 3-4 hrs, mainly just to get the damn lower washers in!

How did you guys get he lower washers in?

Also my WG still closes at maybe .5 hg shorter than it did pre-washers.

I used 2 for each bolt, i think i have to use 4 maybe.

I am thinking about purchasing a very long m8 1.25 bolt, putting it in the top, bringing the whole actuator towards me, to more easily slip on washers to the bottom bolt (i would get a slightly longer bottom bolt too in order to account for the shimmed washers) then i will slip them on the top (the top was much easier)
