Hey scotty thisnis going to be a little all over the place but i have my 02 celica gt 179k miles. I am having a little bit of an oil consumption issue not a whole lot. I cleaned out my pcv valve replaced ignition coils and spark plugs i have ordered upstream and downstream 02 sensors had 2 codes from that. I am very worried it may be a head gasket i had a small amount of sludge in oil cap no bubbleing in the coolant or excessive smoke. Any advice you could pass down for me thank you very much!
Well do wet and dry compression test of the engine so I show one of my videos if the compression goes up a bunch the piston rings are worn you live with that if the compression doesn't change and it's low that would mean the head gaskets leaking on the low cylinders
I will for sure do that! This car is my baby thank you scotty. Will post update as soon as possible!
