This is common on direct injection engines. Many manufacturers went to direct injection, and made a big assumption the intake ports & valves would remain clean despite the lack of fuel making contact with those areas of the engine. What manufacturers are going to (such as Toyota, who has been leading the way), is a combination of port and direct fuel injection. You get the benefits of both with a setup like that, and clean intake ports.
@@SPAZTICCYTOPLASM no oil burning… thankfully, though I have a rear main seal going out and a very very small & insignificant oil leak… either way, thanks! I won’t sweat it.
Technically yes it could, what's the time let me see this on other engines are valve stem seals are shot what you got a really bad PVC system dumping oil into your intake. But luckily most of the engines from back then had the injectors in the intake which get this problem to a minimum since fuel is actually a cleaner as well. On that engine I would use a little seafoam down the intake to clean the backside of the valves I got plenty of videos showing you how to use seafoam to clean out an engine.
