Hello All,
I am new to this club and don't know how to post messages yet. Hopefully I'm posting this message correctly. I have owned my used 2007 Avalanche for over two years now and am just starting to have mechanical problems with it. It is the LT model and has 53,000 mile on it. The check engine light came on a few days ago and the dash text read "oil pressure low stop engine" along with warning chimes to get my attention. I pulled over and called my mechanic. He told me that as long as I did not hear any metal against metal sounds that the oil was indeed getting to the top of the engine, and that no damage would be done. I drove it to him, he attached his snap-on code scanner and it did not throw an error code for him, which he thought was odd. So he suggested that I change the oil pressure sending unit on the engine, which is a common problem with this engine according to him. I did my own research on the internet before becoming a member here and found that this is indeed a common problem with this engine. And that there was a 50/50 chance this would solve my problem. So the next day I replaced the oil pressure sending unit (not fun), but it made no difference. Now he thinks it may be the oil pressure release or relief valve (don't remember exactly which one he said), but won't know for sure until he conducts more electrical and mechanical tests on the engine. My question is, has anyone else experienced this kind of problem, know more about it, or have any advice? If this is something I can do myself I will try, in order to save some money, if not I will pay my mechanic to do the work. Thanks for any input I can get on this.
