    If I wrote this in the wrong place, I am sorry and please move to the right place:
    The question is which engine is:
    - less emergency and creates fewer problems
    - cheaper to use
    - better for gas
    If anyone has any attention to these engines, please write.

    125 gas is better ... because it has valve hydraulics but ... it likes oil a bit. 140 vice versa - it does not take oil but it has glasses - so the regulation costs a little. the failure rate is at the same level.

    it all depends on how you hit - maybe you do not take it at all but ... it is so. to a lesser extent than tsi Vw but always. The most important thing is to check when buying (gray smoke when starting up cold). you can also go along with the selection of oil (I used to have it but the puki car was driving on castrol it did not take oil, then I changed greed oil for lotus and engine consumed 5l / 10000 km). There are oils for "old" engines and you can finally combine them.

    among other things, it may also be black. it all depends on burning oil - large amounts - black, small amounts or coolant in the exhaust is gray. if you do not know, better take the mechanic for inspection or get an expert (cost about 250 PLN). unless you buy from the owner, you can ask him about burning oil - maybe he will tell the truth (eg how much he added, what oil, when the engine was made, etc.).
    generally this engine is one of the better (in terms of durability).

    Only what I know 125KM sits in ZA and 140KM in np ZB, so other years and prices.

    The mechanic will be on the lookout but I have to decide whether 125 or 140. In the future there will definitely be gas.

    so better take 125 - it's better to add some oil PLN 40 than to pay about PLN 1000 for adjusting the valves.

    PLN 1000 valve adjustment? That's it? Why so? What how many km?

    because there are glasses - one costs about 25/30 PLN per piece, i.e. exhaust pumps costs 200-300 PLN (most often regulated) but ... labor wreck - you need to remove the camshafts + a new belt. sometimes a new water pump will come. Regulation should be officially regulated every 30-45kkm but ... you can do it differently - drive until the head drops - the cost is similar but it drags on in time. I had a similar problem myself - I have a motor with glasses and regulation it costs so much (independent mechanic) but I preferred to spend about PLN 1200 for refit of the head and at the same time changed the sockets for hardened (not to burn out) than regulate.

    Are the glasses in 1.6 the same as in 1.8. Last for 60,000 he regulated his colleague and paid 400 zlotys.

    yes - these are the same glasses. but the price falls - where can it be so cheaply adjusted? such price is the price of motor regulation with plates (without unrolling the rollers) on the other hand - in ecotec engines, the valves are adjusted every 150kkm (on the gasoline itself) so it's a bit strange that there were already 60 adjustments - maybe it was a check.

    It's hard to get a good Opel with this engine. Is there any other car with this unit, eg skoda, seat or other car?

    there is no. skoda, seat have volkswagen engines and opel belonged to gm (currently dog-peugeot, citroen) so you will not buy these cars with this engine. This engine (but with the option k7 - to lpg) was still in the Chevrolet cruze and Orlando, but that's not the price range anymore.

    A 1.8 140km in Insignia A? it's the same ? Can it be done in gas?

    all the engines in the insignia are an "ordinary" Opel engine, so it even tolerates lpg well. read the thread from the beginning and you will know.

Topic summary

The discussion compares the Opel 1.8 125HP and 1.8 140HP engines, focusing on reliability, cost efficiency, and fuel consumption. The 125HP engine is noted for better oil consumption management due to its hydraulic valve system, while the 140HP engine, which uses solid valve lifters, incurs higher maintenance costs for valve adjustments. Users emphasize the importance of checking for oil burning and coolant issues when purchasing. The 125HP engine is generally recommended for its lower maintenance costs, despite its oil consumption. The conversation also touches on the availability of these engines in other brands, confirming that they are unique to Opel and some Chevrolet models.
