I’ve had a 15 crew cab eco and really enjoyed it. I was at work one day and seen a 16 rcsb come up for auction at dealers of the Rockies and waited for it. This was all during Covid so you could only bid remotely. The truck came up and started out at $22k. It seemed to have issues running, was already modified for being lowered and exhaust. Nobody put in bids, I offered $15 and the bank settled at $17.5. Got the truck home and immediately new it was rode hard and abused by the previous owner. I parked it, ordered all new oem timing chains and phasers, oem exhaust, updated valve covers, spd downpipes, and oem intake box. Here’s the progress so far.

Of course with anything good there’s always issues. The truck was running pretty good. Noticed some blue smoke from the tail pipe at time on decel and narrowed down to turbo seals being bad. So replaced turbskis.

Running really good, decided to start driving it, noticed a few drivability issues with the steering and suspension. Previous owner used aftermarket parts to lower it and didn’t instal correctly. Replaced lower arms with oem arms and new hubs. Went with Belltech drop struts for the time being until the coilovers are ready.

sounds great, runs really good. After getting everything dialed in, I had gearhead tuning do a tune for it. I wasn’t to happy with it as it left much to be desired. I switched to MPT and had them do a tune. It runs really well and is extremely fun to drive. I did the chains and turbos at 101k and I’m currently at 103k with no issues.

That escalated quickly. Not that i have in-depth exposure or anything, but thats the first 2.7 that ive seen with chain tensioner issues. Is this a common problem with the 2.7? It doesnt appear to have been super neglected as far as oil changes go(very little oil staining inside).

I believe it is the second 2.7 that I have seen on the forum with timing chain refresh, but yea, it's NOT a common report.

Has me wondering also. Was the valve drive done as part of a total refresh based on general report of timing chain failures, or was there an actual problem? The post is somewhat unclear.
Anyway, good work!! Keep it coming.
What/who made the catted down-pipes used? Larger diameters? KM

I’ve done a total of 3 2.7 timing chains, phasers and tensioners. On all 3 including mine, they failed from a hydraulic tensioner and one plastic phaser ring allowing the chains to jump teeth. I thought it was uncommon and was told the 2.7 had the same issue as the 3.5, they just normally replaced motors under warranty instead of doing the timing chains.

it’s pretty clear, you can see in the photos of the chain slop on the driver side phasers. Also is listed in the first post, SPD downpipes we’re used.

I thought the slack was just worn tensioners, my initial thought. The black painted down-pipes threw me off. KM
