98 oil pump for 95 6.5 (929) block?
Read in somebody's post (can't find it now) suggesting the 95 oil pump could be replaced with a 98 pump during a rebuild to increase running oil pressure. So.... I ordered one.
Now I'm wondering if that was so smart.
Will the oil cooler bypass and oil filter bypass valves in the 95 block function properly with a higher pressure pump? And, would the 95 oil cooler and cooler lines handle it OK? The oil pan in the 95 and the 98 are the same, according to the parts catalog.
Would there be any other weak spots in the 95 (929) oil gallery that might be affected by the higher oil pressure from a 1998 oil pump?

Now use semi-syn Lucas 2-cycle oil every fill-up which greatly reduces the frequency of DTC 35-36 codes the PCM/ECM throws.
