Piston Slap: Of Head Bolts, Bad-Ass Sedans…
I just bought a mint condition, dealer-maintained 1990 Cressida. I am aware of the head bolt torque issue on the 6 cylinder engine. The car shows no sign of head gasket issues. My question: should I have my dealer simply re-torque the head bolts? Their tech (30-year’s experience) says he’s done this on many cars with no issues. Your thoughts?
Your tech, the Internet Forums, and my gut agree: DO IT! The information posted in my last sentence’s hyperlink is pretty much spot on, including the technique of doing such a re-torque. That said, let’s get to the heart of the matter.
You have an awesome car! Cressidas get better and better with age, from a design and collectability standpoint. Well, it’s no Supra…but bad ass sedans are just that, son!
Bonus! A Piston Slap Nugget of Wisdom:
LSX-FTW aside, let’s play devil’s advocate and consider a time when the head gasket lets go. Replace it (obviously) because this car is a keeper. But instead of putting the bolts back in (assuming Toyota didn’t used Torque to Yield Bolts) install head studs instead. It’s a great item for peace of mind and possibly even for resale. ARP makes a great kit for Supras, and I would recommend this at some point in this Cressida’s life.
Maybe not now, maybe not even 5 years from now. But at some point, consider head studs.
