You can check to see if it's still in the unlocked position by turning only a millimeter either way but no more or you'll lock it like me. You'll know if it's lockedTorque specs are 10 foot pounds for the small cam caps and 17 for the one big cam capThe way I removed mine is by making sure to mark timing, cracking all the cam cap bolts loose half a turn then loosening them slowly(store them somewhere safe. Then put a bungee cord on the chain so you don't lose timing on the bottom. Pull both cams up to get more slack and wiggle the exhaust cam out first then the intake. Reverse the steps once your change out your part and oil A LOT when reinstalling. Should be good to go🤙 ### ⭐⭐⭐ Tight Fit On Camshaft *by J***Y on Reviewed in the United States on April 30, 2017* I had a little trouble with fitment (very tight fit difficult to get seated). Be sure to be careful of lining up the dowel from the camshaft to the sprocket.Other than that it works great. No timing issue at all. The one reviewer posted it did not work. However there is a solenoid that operates this. Also you need good oil pressure to operate this correctly. ### ⭐⭐⭐⭐⭐ Good product, no problems *by E***S on Reviewed in the United States on October 13, 2021* This was a good replacement. All timing marks in place. Good quality and fit. Better than other brands i purchased that were missing the timing dot --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.ae/products/30322621-dorman-917-257-engine-variable-valve-timing-vvt-sprocket-compatible](https://www.desertcart.ae/products/30322621-dorman-917-257-engine-variable-valve-timing-vvt-sprocket-compatible) --- *Product available on Desertcart United Arab Emirates* *Store origin: AE* *Last updated: 2026-06-04*
