2 questions- Decat and rocker cover seals

Hi all, I have two questions for the knowledgeable folk in the 350 world. 

 

Question 1: My 350z is has an APS twin turbo conversion kit installed on it. When I bought the car I asked the previous owner if he had the original cats for the MOTs but he didn't. I dont think he owned it long enough to have an MOT in his ownership. Will I need to buy some cats before my MOT or do you think the turbos will magically pass under the levels? 
- Can you please suggest what cats I should buy for an MOT?

 

Question 2: My car has just started to missfire. I have now changed all spark plugs and one broken coil pack. The car ran great for 5 miles then started missfiring again. I think the rocker covers may need serviced as I noticed some oil build up on the drivers side (UK) spark plugs. My thinking is that the new spark plugs are now covered in oil and not firing correctly. 
- Do you think I need to order another coilpack that may have also blown and buy some new rocker covers? 

 

 

Thank you,

Are there no cats fitted to the car at all?

 

If that is the case then you will have to find a friendly mot tester or fit a pair of OEM or aftermarket cats.

 

Where are you based as I may be able to loan you a pair of cats to get you through your MOT?

 

Regarding your rocker cover issue, the solution is below.

 

Just give me a shout if I can help further.

Thanks ZMANALEX. I have been lurking on here since I bought the 350z and always see your posts. I am located in central Scotland. Do you still stock the rocker covers? 

 

I am going to pull the spark plugs this weekend and see if there is oil build up on them, then order parts.
