If you’re like me and can’t stand finding oil spots on your driveway, you might want to check out Rennline’s billet aluminum timing chain covers. I’ve been around Porsches long enough to know that the factory covers can be a real pain. They tend to leak and wear out over time, thanks to some questionable design choices. But these new covers? They’re built to last, and I can vouch for that.
Let’s talk about the construction for a second. These bad boys are CNC machined from billet 6061-T6 aluminum, which means they’re not just tough; they’re made to handle the long haul. You can pick them up in a few slick finishes—clear anodized, black, or grey—so you can match your ride’s vibe. Trust me, they’ll look great under the hood.
These covers fit a range of engines, specifically the 2.7 to 3.3-liter engines from '74 to '93, including the 911, 930, and 964 turbo models. That’s a solid chunk of the Porsche lineup, so if you own one of those, you’re in luck. Plus, they’re compatible with any OEM-style gaskets and hardware, which makes installation a breeze.
One feature I really appreciate is the pre-installed 15mm freeze plugs for tensioner mounting. It’s one less thing to worry about when you’re getting into the nitty-gritty of an engine rebuild. Just keep in mind that if you’re working with manual chain tensioners, you’ll need to grab a couple of freeze plugs (OEM# 900-036-008-02) to complete the setup.
In short, if you’re looking for a reliable, long-term fix for those leaky timing chain covers, Rennline’s got you covered. I’ve seen too many folks struggle with the factory parts, and it’s nice to finally have a solid alternative that you can trust for years to come.
