thats a misfire I would say...likely on cylinder 3 as is common....have u compression tested it?

Almost sounds like a bent or leaky exhaust manifold to me

I drove it to local mehanic. The exhaust pipe that comes from all the cylinders moved so the exhaust gases leaked there. He just put it back in place and now its ok. 50€ was the cost

i had the exactly the same problem with my astra mk 4 it turned out to be a leaking oil seal this was causing oil to squirt all over the timing belt causing the belt to stretch changed the three oil seals behind the timing belt renewed the timing belt and tensioner and happy days all was ok

hey, is the problem solved ? I know that when you start the astra, the engine must be at 700tr/min, in case of issue it's 1000tr/min (when the electrical generator of my 1.7 dti isuzu was out of run, the speed of my engine was 1000tr/min without accelerating). Maybe it's a second beld (not the timing belt) issue. hope you'll find the answer !

I had the same problem and the introduction

Check oil pressure, probably one valve dont get enoght oil

What engine is this

your engine is loosing or burning oil. In any case you have to poor some oil from time to time

i had similar problem. solution was in the oil pressure - too low. when i have poured some oil, problem went away. Opel's 16V has problems with something in engine construction and it's cause higher oil burning. GM writes in instruction that this engine burns even 1l per 1000km, but not everyone have this complication. my engine burns sth around 0,5l but when somebody ride frequently, continuous oil checks are annoying...

IDK but knock gotta be fixed before it goes hello from the other side. I think the rpm could be maf , but... god knows .try going to a mechanic for the diagnostic scan, you will know more than for sure

Das gleiche Problem habe ich auch was kann das sein

check oil level with the deep stick.....opel astra G consumes 0.6l / 1000 km (as the maunal says) ...if you drive to long you should do a oil completetion and will sound fine again.

MOTOR YAĞI KALMAMIŞ ONDAN ÖYLE SES GELİYOR

Krümmer bzw -dichtung durch. Hatte meiner auch gerade. Aber nach fast 400tkm darf auch ein Opelmotor mal bissl kaputt gehen. Kleinkram.

sorry for my bad english but this is maybe the hidraulic pistone ! ( ето на български : Ремъка на хидравликата ) remuk na hidravliku

zeker weten spruitstuk pakking

it sounds like you're headed for a bent piston if your engine overheats, does it overheat? :/

Könnte Problem mit Wasserpumpe und spannrolle sein. Der Zeiger der Spannrolle schlägt gegen den Kranz der Wasserpumpe. Dies führt zur Zerstörung des Kranzes und dem Zahnriemen. Motorschaden droht. Motor abstellen. Prüfen ob da alles in Ordung ist und keine Metallteile sich gelöst haben.

Este motor 1.6 é bom ?
