Oven cleaner method saves alot of time and work.
@CoolAirVw
Жыл бұрын
Sure if your doing it yourself. Maybe oven cleaner will fix it if yours is "just barely" stuck. maybe if your doing it yourself and don't have to GUARANTEE to a customer that it will be FIXED. Maybe if your reputation doesn't rely on fixing it right the first time.
When using the wire brush on the ring, it's a good idea to use it on the outside edge of the ring too. There are three (I think) raised portions that hold it in place and they are common places for carbon build up to cause sticking. Once reassembled the whole vnt mechanism should move with a VERY light touch, even gravity should be able to move it.

Very good video. The problem is often to R&R the damm turbo,the repair is easy by comparison; And here is lesson learned when you have a variable geometry turbo (means with those "11" moving small wings/vanes): Do a varied driving--- if you do city slow driving, find a stretch to floor it ,every hour or so; if high speed driving or towing,let off the gas often,to get those vanes moving; The first case tends to avoid the vanes getting stuck closed,no boost; The 2nd case,them getting stuck all open ,causing what we saw here,overboost; The worst invention ever for diesels,the EGR valve is mainly to blame for that problem,it makes the engine constantly re-ingest its own vomit,its own smoke over and over; If you only saw what the EGR can do on older cars,to clog up intake manifolds, throttle valves,cyl.head intake tract,valves, rings,etc to the point that the engine is choking and barely runs; it then pollutes *A LOT MORE* then if there was no EGR in the 1st place; this mainly due to the rings getting stuck with all that muck,and the cat.having seen better days; it's a tough decision bet. breaking the --LAW-- and eliminating --EGR-- (not easy on some cars,it turns the CEL on) or keeping it and facing those consequences...

I ran into what may not be common problem. I found the plate in the exhaust housing below the vane plate had rust developing under it. This was raising the plate just a few thousandths of an inch. So when I tightened the vane plate it would cause the vanes to stick. I found the sticking was gone when I loosened the screws holding the assembly together. So I removed the plate, cleaned the rust off and it works perfect now.

seen that before. unfortunatly sometimes when you pull the screws out of that plate the bolts break. At that point it might become a replacement turbo. We try not to pull those bolts if we dont have to.

I'm getting 15-16 inches of boost and the car feels like it did back in the day. I dissected the actuator and it was all rusted to the point where the diaphragm had a hole in it.
