Hi, have I read previously articles that the C20NE should be a freewheeler. Is that true? Now to my question: Soon I would have to change my timing belt, because of the 5 years time interval. Since the C20NE is supposed to be a freewheeler, should there be nothing happening there, or? Wouldn’t it then simply be possible to drive around with the car for so long, until the belt then snaps at some point and I let it change first???? stay and have to be towed by the colleague is already clear to me, but I like to accept that 🙂 mfg David

Moin! After a long diagnosis I found out that my E-Kadett (C16NZ) no longer gets the ignition time adjustment richitg baked. If I slowly give gas, he comes with (in the stand). If I give gas quickly or during the ride he starts to jerk. When I flash I noticed that in this case he seems to make the adjustment in the other direction or even nciht! What can this be about??? Have already tried some things/renewed and now doesn’t know any more… Ask for either good tips or a description of exactly how exactly the ignition time adjustment at Multec runs or is regulated… Thank you!

Moin, I wanted to know what you can do with the C14NZ and how much it costs and what it does (in terms of performance)? I also read somewhere that you can install cylinder heads from the C16SE or something like that, what fits on/to the engine block (inlet bridges, exhaust manifolds, etc.) and what does that bring? Since I already have the engine there, I want to install it, so no C16NZ or something to install it. … know a side where there is a instruction to change camshafts, manyleic ht equals the C14NZ (possibly with pictures).

Hi, because I had a gearbox damage to the Cali a short time ago. Did I throw out the F18 and built in a f20. So I have now original swing plus old clutch. Expression bearing as well as levers of the F18 (with matching sockets because the lever is thicker than the F20). Now to the problem: When assembling it I noticed that I had to adjust the clutch rope so that the pedal has the right position. Unfortunately, the clutch does not separate properly. What could this be about?? Is the clutch cable in the f20 Kürzer as in the f18. What is the difference with the F20 with service flap and normal F18? I always thought they are the same except for the flap. Thanks already for your answers.

Hello guys, have built me a 2.7 Cih with 2.2 head and 296 shaft presses at the time 187 HP. Drive it with a 2.0 LE Jetronik and BMW air volume meter but with the inn life of 2.0 Opel. Think he gets too little fuel top or from the middle of the rotary zalband. Starts at 1900 with 247nm and pinches at 4500 and comes back at 5200. Search a injection system of a car with more displacement without ignite adjustment like our LE Jetronik hurts what comes to mind??? Or does someone already have the 2.4 Motronics at the Old Block brought to run??????? Thanks for the tips LG Joe Ascona B 2,7

Hi, was on Friday in the Bosch workshop once due to track and they had there test bench there. After a short consideration I am over there.. Bad thing. Someone stole power from me.. Z18XE, F13CR, EDS Phase 1, E85 with Piggybox (but goes from the speed/acceleration like SP, if not better), 147 Tkm on the clock… Performance : 786 KW . It should be 92 in series and 103 According to EDS. Well, what’s going on there?? danger was something around E20. And Piggybox. However, the P was a little funny, not a blower, on the expression you can see not even the revolutions, but only km/h and kw, not even NM or pressure.. What do you think the result is useful or for the ton? If useful, who stole my performance? At the expression of the funny test bench. Still, that is a freeman with a Bosch test bench, not an original boot service.

Hello, after the question of the best 16V engine of all time has arisen in the Calibra forum, I would like to start a thread. The C20XE is always called one of the best 16V engines in the 2-litre class. I had a long time such an engine (with considerably more than 150hp) and was really enthusiastic. However, there are certainly other manufacturers that have put the good aggregates on their feet. For example, I think of the S14 engine (built in the E30) M3 and E30 320is). I would particularly like to address the 2.0 version of the 320is (192hp) because it has the same engine capacity as the C20XE. The 320is is even better from the basic data (specific power, specific torque, medium pressure) than the C20XE. However, the C20XE is at the forefront of the specific efficiency. One should perhaps also say that the engine of the 320is is quite at its development limit (single throttle is already standard). Here is a link to the test report of the 320is. I ask for a factual discussion without polemics and regular table holds ciao

Hello Motor Talk municipality. Now it’s time, the cylinder head is down and now the piston rings are replaced with it. Last time I renewed the valve shaft seals, but the oil consumption is still at 1 litre at approx. 800- 1000 km. The mileage is currently 65,000 km. What causes me to break my head are the numbers on the piston, I once put 4 pictures of the pistons in here. It stands here on the piston 2 times H08 H4 (pistons 2 and 4) and 2 times H09 H4 (pistons 1 and 3). So the number H08 for pistons with 79.08 mm diameter, H09 for 79.08 mm or am I wrong here? I will measure the cylinder diameter tomorrow, if I pulled the pistons and put them in here. In addition, I took pictures of the piston combustion chambers from the cylinder head. Oh yes, there are still mock marks on the cylinder treads, only the photos will not be so good, will take pictures tomorrow with my son’s camera. uch im vor out for numerous tips and opinions. Greeting Werner

Hello guys, I changed the shaft seals 3 weeks ago – so far so good.Blues at the start is almost gone. Only now I have a new problem – when I stand at the traffic light and then just play with the gas, he squirts out in the back as if I are in the high moor in England – complete fog. Were made: shaft seals changed oil 5W30 as well as filter changed intake tract cleaned hollow screw cleaned etc. What makes me wonder, that if I have the oil measurement sta b pull, the speed drops! The same happens with the oil filler cover – the speed drops. I have problems since the oil change also with dm idle, although the idle control seems quite clean. I get here slowly the Macke – are it now the piston rings??? Still to the info: mileage 185000 Km Thank you, if one has THE idea. Michael

I asked the question already in the Vectra-C forum, but so far I have not received an answer to it (link to thread ) From a commonrail technique book I could actually only read out so much that a re-injection takes place only when a regeneration cycle of the DPF is initiated. An employee of a technical hotline said however, that there are also diesel engines, which carry out a re-injection under “normal” conditions. I had the latest engine management software installed by Opel. AGR, differential pressure sensor, charging pressure control valve were replaced, and the charging pressure sensor was cleaned. However, with a borrowed Gutmann tester I could observe the following values: 8mm3/Hub in idle mode and 60-70mm3/Hub in load mode without gl of course, if this is normal. Based on the fuel consumption, I would tap on something that is related to the DPF. But it actually looks quite good or the loading condition of the DPF changes regularly according to the tester, and according to the display about all 800km is burned free. What surprised me, however, is that the differential pressure showed no matter which loading condition -19mbar (60% loading u.a.) However, the sensor was replaced half a year ago, and the cables were checked for leak/permeability – all in all MfG eyewitnesses
