In that engine the lifters are in bores which are cast into the camshaft bearing carrier, If you lift the camshaft carrier without holding the lifters the lifters will fall into the head cavity and you will be really sorry.

The magnets basically stick to the lifters and the wire sticks to the magnets - so you can lift out everything as one piece. The original service tools are little suction cups.

Oh, thanks for the reply:)

Now I understood the reason why.
And yes, he mentioned that the proper tools were suction cups. I loved the way he lubed them, using a Large vial and a vacuum pump:P

It's so interesting to watch people overhaul engines lol. Tiny bits and blobs fit in there bla bla.

it takes an experienced hand to remove the camshafts from this engine, I had one car 1993 528i delivered to me in Karachi with a broken camshaft from some mechanic in some top shop in Karachi hamfisting it, had to get one from dxb and installed it correctly myself.

Yeah, I can remember that he loosened bearings in this sequence to take pressure of the cam shaft-

First, E1 bearing cam lobe was at TDC, then he went to the left bearing i.e E7, used a wrench, gave it a turn so the cam lobe faces were up, between E6 and E7. Then he proceeded to loosen every nut on the bearing E7-E1, except for E2 while his assistant was holding the wrench tightly, to avoid the cam shaft to move.

Then he loosened the nut on Bearing E2 slowly, turn by turn to relieve pressure of the Camshaft and he Turned the cam shaft using the wrench a bit as well, so it wasn't tight, but free, in a comfortable position.

Our mechanics go by instinct and when something messes up- blame goes to the manufacturer lol.

its basically a very simple thing, you unload the lifters by forcing the cam to sit in a position - you need to hold it there, the cam in this engine is really long and hollow if you load it sideways slightly it will break, if you drop it while carrying it, it will break, if you dont put it on the bench gently it will break. Its basically handled like glass.

I use my pinky finger to rotate the lifters to verify there is no load from cylinders 2-6. Saves using the factory tool which is pricey. I use small suction cups to arrest the lifters - the stems of the suction cups have holes in them to pass a wire through them just like this guy did with magnets.

I dont use magnets as they can magnetise the lifters and cause metal particulate to be attracted to them causing quick wear.

my car's starter is acting up again, we had replaced the starter with a kabuli one 6 months back and the old problem is occurring again. when the key is turned the 3 red lights in the meter go dim and i hear a click sound, if i hold it like that sometimes it starts working after a few seconds, sometimes not.

battery shows 12.3 volts after the car is back from a drive and 14.4 volts when idling with headlamps off.

the lock has been replaced one week back because the old lock was abit loose and we suspected it to be the cause.

please instruct me a way to trace the faulty part.

[Xulfiqar]

get a headlamp bulb or sealed headlamp 55W type. wire it up to the starter small wire - when you turn the key the lamp should glow very bright, If its a bit dim then your wiring is faulty - most cases the ignition switch is bad, other cases is that the grounding is bad.

Old wiring and old connections and starter usually are a time eater to troubleshoot, but not too bad.

@xulfiqar AOA Sir, Ur expert advise required.
I am using city idsi 2007 from last four months driven almost 75k with no maint history.It has started consuming engine oil and giving blow at high rpm.In the morning when I start for idling it gives blue smoke for sometime but engine also throws water. At high rpm smoke is black. Honda 3s say engine need overhauling. Please advise.

@xulfiqar
Is it safe to use caltex delo 15w-40 in cuore done around 115k kms?
I was previously using shell helix but it is now api-sn and you told us that low zddp levels can be harmful for this engine.
Any other oil you would suggest keeping fuel economy in mind.
Thanks in advance:)

btw which engine oil you are using???

Xulfiqar bhai, your kind help is needed. Im looking for used 2006-7 Vitz 1000cc, the issue is that 4 cars ive checked give white smoke when accelerator is put to the floor for about 5-6 seconds. The dealer said that it is "kacha" smoke caused due to detunded tuning of engine. Please explain the reason for the said scenario, thanks.

shall I go for overhauling ?
does engine need complete overhauling or some part work req ?
Engine efficiency after overhauling?
Good Mechanics nd oem in Rawalpindi & rough cost
w8ng for ur expert advise.Thnx

[rustam54]

as of now without Xulfiqar place is like this

What happened to the gears??

Or did we just switch to CVT with modern demands??

timing has to be advanced for your engine to work properly on CNG

I think you need to get your car tuned on cng
