Help, strange vibration/ rumbling through car

[Simaroon]

I\'m almost positive I\'ve dragged gunk into the filter, I\'ve got a new one ready to replace it

Check the vac line running to the pressure sensor, if you have a pfc have a look at the pressure reading when the car is ticking over. If its showing no vaccum check the pipe first. Car chucks loads of fuel in.

How hard is the car to start ? Pulling the plugs out and turning the engine over without the egi fuse in will at least give you an idea with a basic puff test.

No idea how the first post was missed, and can understand the frustration, hence the second post.

Real sorry to say it sounds like you have lost an Apex seal and taken the others out, I drove my FD back from Silverstone years ago with symptoms like this after literally hearing an Apex seal rattle down the exhaust pipe

Really hope I\'m wrong, but you really need to find out if you have compression by taking one plug out, turn it over on the starter, listen then put it back in and then do the same to the other rotor.

This way you will know what you have straight off without spending time and possibly money in the wrong direction.

Thanks for the replies

I haven\'t got a pfc but have a boost gauge so could check vac? I\'ll also check the vac line to sensor, thanks, and take plugs out on weekend to turn the rotors.

I have an awful feeling it\'s died

Maybe nasty fuel in the lines? Has been stood a while

There are  quite a few youtube videos to watch with 7 s with blown tips....might be worth checking out if yours sounds similiar.....mine sounded like a chinook! lots of engine shaking no power dieing out. fingers crossed its summit else...as grinder says pull the plugs....thats how i diagnosed mine 10 mins easy peasy ( make a note of your leads positions).....back of hand by spark plug hole front and rear rotor...no air pulse...no tips....PULL THE EGI FUSE FIRST!... no smoking either.  good luck.

Any update on this...

I havnt long got back into the house, I\'m trying to upload a vid to YouTube from my phone.

I think it\'s died

I took out the top plug of first rotor and then the 2nd rotor.  The pssh noise was loud and clear from the rear rotor, hardly noticeable from the front although still a constant \'beat\', just not a loud pssh. Guys on other forum instantly stated this is a sign of no compression on front rotor gutted!

I don\'t really know where to from here.

sorry bud tips/apex seal blown on front rotor.....

my front rotor blew last year mate...know how it feels i was gutted ....got a few choices...rebuild or sell spares repair .
 

prob best to upload to photobucket.

What did you choose to do? Mines still totally standard twins rats nest jobby. Might be worth simplifying the nest while it\'s out,  want to keep twins really.
I\'m nowhere near the funds for a rebuild yet tho I don\'t think. Did you do the 2 rotors while it was out?
It seems like a minefield of choices and decisions.

I\'ll try photobucket now thanks.

I sold mine spares or repair wasn\'t an easy decision but moving house so that took priority.
