Hello,
swapped out my camshaft for a newman ph2 lately. When starting car the chain tensioner didn't open so I heard a ticking noise , stopped car , reinstalled tensioner extended and it all started fine with no ticking .

Car hasn't felt correct ever since. On inpa at idle stft readings go from -5 to +8 or so. The issue is when I apply gas it goes to -15 all the way to -30. With timing advance show 50 at times. Had a rich code last week so I took to mechanic.
mechanic believed it was timing so he redid timing and timing chain . I checked inpa again and same scenario is happening , high negative stft that get worst when stepping on gas pedal. Car feels like less pep then when I had stock cam . Had adrian update tune for the cam when I put cam in .

Has anyone come across this when swapping out to a newman ph2 or any guidance as to what can be causing this ? Mechanic said he did smoke test and dint find leaks.

Mods are ...
2004 mini cooper s
Gp intercooler
380cc bosch injectors
1 step colder plugs/wires/ screaming demon coilpack
dt bypass valve
gp intercooler
newman ph2 cam
Ddm intake

Thank for any help or guidance

 

Cam or crank sensor ok ? I had issues after my head n cam swap and after tearing it down 3x I finally found I had pinched n put a slice in the crank sensor wire . Not saying that's your problem but maybe one of the sensors is bad

 

do a comp test, I was one tooth off and found it with a comp test. is the mechanic one that specializes in mini? If he turned over the motor at all with the cam bolt it will jump a tooth. It's unique problem with R50/R53s

 

i haven't swapped out either one to be honest. I have replaced the orings on them while doing other work earlier on the year. They never really gave me any codes . I have looked around quite a bit ,but haven't really seen anything looking " broken" would the cam sensor cause an issue with over fueling?

 

Unfortunately not a mini specialist. They claim to have over 8 years working in European cars. Not very many mini specialists around where I live and the one I found was way too busy and.is quite a ways away.

He did Do a compression test and said that he did feel some air passing so he determined it pointed to a timing issue. They clain to have reajusted the timing and replacing the chain and guides while in there. Now I am not sure how accurate they were in resetting the timing .

 

honestly not sute so can't answer on that buy if you havevinpa you can see most your sensors running in real-time and ask on here what should be with in spec numbers you should be seeing.....idk if itle help but maybe try resetting the fuel adaptions ...

 

Thanks Minimanadam,

Actually I do have inpa installed and adrian looked trough while doing my first tune to accommodate all other mods before the cam . Then had the tune readjusted after the cam install to include the cam .
will have to look into each reading more, but my knowledge is limited. I may have to invest in a good data logger and hopefully that will help to pinpoint to a more direct issue.

I am starting to wonder if the fuel pressure regulator is failing and causing too much fuel being put in . I did redo my injectors to bosch 4 port a while back as I was smelling fuel in my oil. I did smell quite a bit of gas in the intake and cooler last time I removed it.

 

mr.Blah,
can I ask what signs were present or how did u diagnose the timing off by one tooth via a compression test?

trying to figure a few tricks so i can perhaps test myself without removing timing plate and all that fun stuff. I am not 100% confident the mechanic got the car in proper timing to be honest as it is feeling the same . Could be another issue but would like to rule out timing for sure first .

 

if you only did just a cam swap , you really don't gain much more than 5hp..if anything it just changes around the Powerband..when I did both my bvh , street cam and few other bolt ons with it . Even then there wasn't a big enough power increase to really say " wow, that helped ".. I mean it did but not like I had expected as I felt more on other vehicles I did the same mods to..

 

Yes I understand what u mean that a cam swap will not add that "HUGE KICK IN THE PANTS FEEL" , but depending.on the cam specs and band power range i should have definitely felt some type of improvement at the 3000 rpm and up....

The issue is that the car has changed and feels that it actually has less power and less pull then it did before the cam swap. With the mods u possess I would have really tought ur car would have a very nice power range .
