Hello. My name is ***** ***** I will be helping you today.My first guess would be bad apex seals.
Customer: replied 1 year ago.
apex seals, are those something we can replace or are the machined on.
Expert:  Wayne Crawford replied 1 year ago.
Thats a kind of loaded question.They are replaceable but basically when youre getting that far into the engine its time to do a rebuild. You have to take the whole engine apart to do it. The apex seals are on the tips of the rotor.
Customer: replied 1 year ago.
hey is there any type of tool we need, to do this apex seal
Expert:  Wayne Crawford replied 1 year ago.
You will need several tools. You need to remove and disassemble the entire engine. If youve never done it before your best bet is to start by getting a service manual on the vehicle and reading through the engine teardown and rebuild. It will tell you all the special tools you will need to do the whole job. Thats a lot of instructions and beyond the scope of what we do here.

i underdstand, we are an auto shop and work on a wide variety of vehicles, however this is the first rotary, my specific question is wether we would need anything outside the ordinary specific to this motor besides what you would typically need on most standard vehicles....outside jaguar , saab, bmw and such?
Expert:  Wayne Crawford replied 1 year ago.
No. Its a pretty simple design. You will use your standard pullers and bearing seperators and such. If you have a decently equipped shop you will probably have something for everything you encounter on there. You wont need any special service tools just for the rotary engine. If you have all the tools to pull apart a saab or volvo and put it back together you will be set.
