Troubleshooting the Venture engine is not simple a matter of changing a few components. The factory service manual is several hundred pages long and tough to read. I would first suspect a blown intake manifold gasket or cylinder head gasket(s). If you have oil pressure problems, loss of coolant, and/or overheating that is where I would go before the computer system. I landed up changing out my engine with a junkyard engine. Runs fine now. If you need more email me direct: lloydballard hotmail.com.

Had the same problem. Ended up being a head gasket. Lots of money to fix. I used STEEL SEAL cost me $80.00 and it is still working 2 months later. I average about 400 miles per week on my 2000 Venture. I had no signs of water in coolent or blowing smoke just constant high pressure in cooling system. Hope this helps.

Could you clarify your symptoms? Think you meant to say no oil in coolant or vise versa? Also what do you mean by high pressure in cooling system? I think you mean the coolant was boiling over? I am tucking your suggestion to use Steel Seal away incase my engine acts up again. It appears to have a small leak that may be triggering a check engine light for a catylatic converter problem.
