(Firs off, sorry to rez and old thread. I figured someone looking for this information might be benefit from the following.) All the VQ35s had oil consumption issues: The HRs were mostly limited to ring issues. That oil consumption is presumably dependent soley on driving style (according to Nissan testing and reports). There was a test done by Nissan and a correlating TSB to test for oil consumption [as well as a recall based on the outcome of that test]. (The recall included swapping out the entire block...) Nissan took two 350HRZs and two drivers which were to drive the vehicles differently. When they swapped cars the oil consumption issue was greatly minimized on the one and greatly increased on the other... No chain guide issues on the HR. The DEs had the oil pres. drop from the timing chain gasket, piston ring issues, timing chain guide problems, and the notorious cat. issue. (Not that I think all of the aforementioned should steer you away from purchasing this engine. In most cases simply watching the oil and oil pressure gauge is enough. The more serious consumption issues were from people not carrying out proper PMCS.) FWIW - Remember that the VQ35DE had 2 blocks, the FWD and RWD; you will obviously need the later of the two. Hope this is of help for those who might be looking at this thread.
