Well, while you're here check out my cylinders I just borescoped and let me know what your thoughts are. I'm doing this primarily because I've been experiencing higher oil consumption in the past +6 months of 1qt/3hrs. (Yikes) Only fill it to about 6qts and tend to change oil every 25-30hrs. No metal in the filter in the past 3 changes and oil analysis comes back normal for my 1430hr engine. I've also had abnormally high oil temps with low to normal CHT's. (Granted I live in ABQ but never seen oil nearly red line before). My initial thoughts are increased blow by due to frozen or broken oil rings hence the oil use/ higher temps. I just completed the oil control ring flush yesterday but haven't ran it yet. So, check out the pictures in the linked albums and let me know what your thoughts are. I believe I see a good amount of lead deposits on some of the cylinders and oil pulling as well. Below are the bottom spark plugs for reference too. Nothing crazy or out of the usual for residual oil from my perspective. https://photos.app.goo.gl/p4o59zXnJ8sN8smbA https://photos.app.goo.gl/wdjMyvKrDWE2V5wA6 https://photos.app.goo.gl/AXtSkn4HXR5t8Atr9 https://photos.app.goo.gl/pAVCbk2QWQgWpvoF9 In the meantime, I'm trying to pull the vernetherm to test if it's working correctly but it's being a real PITA. The return line from the oil cooler is getting in the way so seems like I'll have to pull that as well. I'm also trying to re-install the oil regulator so the bypass holes line up correctly but will need a new crush washer for that. (Mines the non-adjustable kinda adjustable with washer type.) Let me know what youses think! -KC
