just got a 87 rx7 with a 13b n/a and lots of extras in the **** pitt but it well not pass air care burning oil i know i need a new cat and have no clue past that any one

 

Rotaries add oil into the mixture of air and fuel into the engine to lubricate the system. So about every 1000 to 3000 miles you use up to a quart of oil. If it burns up more than that you should see if you have a leak first.

 

sorry for being a little vage it's bruning a lot like i can leave a smoke cloud it's leaking a bit of oil out side the block if it can help this is what i scored at air care
hydrocarbons-737.00
carbon monoxide-3.46
oxides of nitrogen-204.00 i passed on this part
failed every thing else i have to get new cat would that be the rise

kinda need like a check list of things to do to get this heavy oil bruning to quit
thank's

 

oil rings? if you rev your car up to 4500RPMs does the smoke come out in excessive amounts?

Download the FSM also. Post #8 in the FAQs (i've posted this at least 5 times in the last 2 day.)

 

yes it dos get thinker and my oil gage stay's at 0

 

a new cat will get some o the emissions down, but also try a new set o plugs, an oil and filters, getting the injectors cleaned can also make a huge difference, im not familiar with canada but its all the same ***** in the end
Get your timing checked as retarded can cause extra hydrocarbons too, alot of simple serviceing can solve these things, throw some new ignition leads at it if they are old as well, as some small missfires that are hardly noticable can hurt the tests results

Get the oil pressure tested first, guages are faulty at best of times

 

your oil control rings might be toasted. rebuild time?

I'm done searching. Start reading and searching now.

 

thanks you guy's info very helpfull well keep in touch let you know how it's going

 

changed out the old oil and oil filter and new stuff on and in havent cranked it over yet oil was nasty as hell looked like coca cola and thick

 

i cranked over my rx7 and now it stall's after 3 to 9 sec's and all the dumby lights go on i think it's stallin from the new oil i used 10-40w pensoil

 

It probably had Lucas Oil stabilizer in it to cut down on the oil consumption. I tried it some, as my control rings are getting old and my car will smoke if you rev it really high when it is not fully warm.

I do not recommend Lucas oil stabilizer at all, I was not impressed with what it did to my startability.

I expect an engine to smoke with almost 200k on it, so I am ok with it.

Yours sounds to be way worse. Mine will only smoke like that under certain conditions, yours all the time. I recommend a rebuild before carbon lock sets in.
