Omega General Help / Re: cylinder head removal

« on: 25 June 2011, 12:18:10 »

Thanks you for your reply. So the power steering pump must be removed in order to get the bolt off which holds the pipe, lifting bracket & dipstick and for the removal of the exhaust system. To remove the exhaust system of the other cylinder head the long metal coolant pipe (and alternator although in the picture the alternator is still on the engine) must be removed and its fixed by two bolts on the backside of the engine.  Haynes says unscrewing of the oil cooler bolts is neccessary allthough there is room for unscrewing the two bolts when the other cylinder head is taken off and Haynes did not mention that you have firstly taken off the right or left handed cylinder head.  Perhaps I have started to short to get enough oil pressure to the oil filter (the oil pump pressures oil to the oil filter and from that to the oil cooler. Before I started I had renewed the oil filter and oil cooler so the oil filter and cooler and pipes where dry because of the renewal).

I did for the first time the oil cooler and timing belt. I took the oil out before changing the oil cooler for a new one and put fresh oil and a new oil filter in the engine and saw that the level on the oil dipstick was allright. I started two times less then a minute (the engine did not work during that time) but made a mistake with the timing belt and the valves are bended and so I have to remove the cylinder heads to bring them to a machine shop. I wonder if  skimming of the cylinder heads is necessary. In Haynes is written that you have to take off the oil filter and oil cooling pipes before removing the cylinder heads so I took the oil for the second time out of the engine. I was completely surprised when I took off the oil filter that it was completely dry with no oil at all. I am wondering about the reason. May be the oil pump was pumping oil when I started two times the engine but the oil did not have had the time to reach the oil filter yet (and when when the engine is working the oil reaches the engine). I hope so (or the oil cooler pipes are damaged on the backside of the engine -as far as I can see they are undamagad- or may be I placed the oil filter not right). I am in doubt what the reason could be for the dry oil filter.

Thank you for reply. Standing in front of the omega its the right cylinder head and the steering wheel also on the right  (I am dutch). For this job I am folowing the haynes service manual.To remove the exhaust system from the cylinder head it was neccessary to remove the power steering.  But seeing the cylinder head I think that it might be possibible to remove the cylinder head without removing the power steering mounting bracket (to remove the bracket its neccassary to remove the airco compressor and therefore the refrigarant circuit has to be discharged by a air conditioning specialist and I hope thats not neccessary).

Is it possible to remove the cylinder head without removing the steering pump mounting bracket and dipstick tube. I have a omega with a x25xe engine from the year 2000 with a fully functional airco system.  Does anyone have done this before. Many thanks for your reply.
