Ali-d1936's S15 Spec-R

[ali-d1936]

fucking getting plagued with a little miss the last few weeks, its not a full misfire, but idling its rough and every now and again the car jerks a little, i thought it was a boost leak/bad earth/coilpack. so went over the earths and all was ok. so i took off all the pipes and looking into the intercooler the bottom inch was full of water

this is the result of a little tare on a silicone joiner, but on the upside that pritty much guaranteeing that i have a boost leak somewhere

(dont worry about the oil in the picture i was cleaning the joint in prep to put back on read somewhere a smeer of oil on all the joints helps with a seal)

so i drained it out and put all the pipes back on but still have it but its better than it was, so im stuck till i get the replacement joiner

so with the water drained from the inter cooler i was wondering if any damage was done,
so i bought a compression tester,

and happly it showed 145PSI on all 4 cylinders,
of course i got proof the best of the 4 photos i took >


some might think thats a bit low but reading up online iv seen people with 120psi and still have strong engines, so im happy,

i think its good for a car with 207K
but ill do a wet test soon with a spoon of oil in each cylinder and see if it changes much


but one look at the plugs and i knew they had to be changed,

E78 for 4 new denso plugs recommended by nissan

old v new


took it out for a quick spin so make sure everything worked ok,

and
Oh
My
God!!

the difference was black and white same kind of pick up low down but as the revs climbed the diffrence the new plugs made was unreal!! (not suprised as the old ones looked past there sell by date)

so latley iv been wondering what Mpg i was getting and its working out at 24MPG taking the average over 4 full tanks.
so now ill do 4 full tanks again and see if the new plugs and no boost leaks give me better MPG

ah and this is what you car looks like when you use it every day




ill get around to washing it some day
