Hi again lol,

Ok, i have an Ecotec X20XEV, just lately when it's cold it's been sounding a bit rattly and juddering a bit, lasts about a min and then it kinda changes rev tone and drops to normal running, the rattling is still there for a bit longet then that disaperes eventually and it all runs normally, however, as well as all this i get alot of exhaust fumes and a smell of it running rich (petrol), it also pops alot when i rev it up, anyone got any ideas ???

Thanks again :sorry:
 
right the rattling is probably the tappets and the smell of fuel/popping could be over fueling cause by faulty cts, not sure where that is on your engine but im sure someone will be able to tell you

Is there anything i can do about the tappets ?

Also (sorry but i'm dumb) whats the CTS ? lol

:hang:
 
erm ive not seen the tappets on a xev sorry, its not that hard though, you just need a feeler gauge and a few basic tools

Is it a serious thing as they dont rattle when warmed up, dont wanna be spending loads of money that i aint got really and i'm soooo not mechanically minded, ask Max and Cliff lol

The CTS is a blue or black plug to the right of the head between your egr and dis unit, easy to take off and on. They're about £15 from a motor factors iirc

Thanks mate, i'll have a look this weekend i think :rolleyes:
 
no feeler gauge is probably the only thing you will need to get tbh, im pretty sure that yours will be adjustable with a spanner unlike mine where i have to replace the shims
 
yeah, if you have a haynes that will tell you how your tappets are set
 
Hi buddy,

Your car will have hydraulic tappets. There is no possible way to adjust them. They are most likely gunged up slighty. I wouldn't worry too much about it, as like you say it quietens down when the engine warms up. When was the oil and filter last changed? I would also give the car a fully service as well whilst you're at it.

If the revs are sticking slightly, I would give the throttle body a good clean out with some carb cleaner and some rag (available from any half decent motor factors). Due to the breather system of the engine, oil vapours travel from the cam cover into the inlet manifold, so over time you will get a sticky throttle body. ECOTec's are a favourite for doing this.

Hope this helps and you get it sorted

Thanks mate, gonna give it a service this weekend, gonna stick some lifter treatment through and then drop the oil and replace, replace oil filter and get my new plugs in too see if that helps, i'm just a bit concerned as last time i tried to clean the ICV and EGR i cross threaded the damn bolt and ended up making a real mess of it.

It's the wheels i'm really worried about at the min, they rubbing on inner wheel of passenger side and it seems to be sitting lower than normal, well lower than a 60mm drop all round can get anyway lmao :doh:
 
ahh someone who knows the specifics! sounds like your on your way to fixing it mate.

as for cross threading, when replacing something make sure the threads are clean and before you do it up unscrew it a turn or so to seat the thread properly

Thanks Tom,

I'm no mechanic but i know a bit, never serviced my Astra before but willing to give it a go, can't be that hard surely, do i need any specific tools to service the car, i have tool kit with sockets etc in it, not sure how to get the sparkies out exactly, i've seen a specialised tool in halfrauds before, not sure if i need that.

In terms of the cross threading, for the ICV and ECG it just seems soo damn fiddley, especially the ICV if i remember the lower bolt is on it's side and really hard to get into !!
 
you need a spark plug socket and extention(size wise not sure but you will probably have one in your pocket set, jack, axle stands, big muscles or an filter remover, probably the odd screwdriver and i think thats about it. Its not too hard to be honest but as always first time round use your head and take it slow.

Thanks mate, gotta find me some axel stands, had the ones i own pinched, i'll have a look on e-bay for the rest of the stuff
 
Hi,

You have the same engine as mine - X20XEV.

poor idle-
From start up (cold first thing in the morning)... It is norm for the revs to be very low (like 500rpm) until after a few seconds it will re-adjust and idle correctly and suck in more air.

Tapping noise-
Your lifters are probably in need of a clean (as people have advised above) but to be honest... I wouldnt worry so much if it stops after a bit (same as mine and many other cars)!

Petrol Smell-
Could be your tank leaking and can be hard to spot (mine leaked around the seam and was hard to spot but put a new one on and it sorted it).

Anyways... good luck!
