Low/No Boost still?

[CodyTY23]

ok i changed the cat on the Ty and thought that might fix my boost problem but it didn't it keeps getting worse with the more i drive it so it is officially parked. I have no idea what the problem could be! I am lost can anybody help? I also think the oil sender is bad could this cause the no to low boost?

Re: Low/No Boost still?

Do you have an intake traqck leak? Are all your hoses clamps tight? Is your wastegate rod set properly to its close with a slight amount of tension at rest?

Compression check?

Split hoses from the turbo to ic or ic to tb?

Major exhaust leak

turbo compressor fins intact? turbine fins intact?

could the oil sender have anything to do with it?

Re: Low/No Boost still?

oil sender wouldnt have anything to do with it, if it was bad you motor would be bad. your turbo is tight, you pulled the hose off and checked the compressor for in and out play, side to side

No. I assume your talking about the sending unit connected to the oil pressure guage, it doesn't connect to the ECM. The oil pressure switch if bad would cut off the fuel pump.

Re: Low/No Boost still?

should there be any play in the turbine? should it spin very freely?

Minimal play and it should spin easily by hand.

Stock WG's are a piece of shit...make sure its not sticky as hell. If you have the hard stock vacuum lines, I don't care if you checked and triple checked. I bet that is your problem. A visual check is not worth much. You need to preasurize the system to really know for sure. i.e. Bike tube trick
