1996 960 cam timing 900

Hi Everyone. It's been a long time since I've been here, owing to major back surgery, gout and a broken foot. I had been neglecting my poor '96 960, but the engine was making noises that got bad enough to make me park it for two months. When I pulled the timing belt front cover off I found the tension and idler rollers totally disintegrated, no bearings left, and the idler shaft worn nearly away. To add insult to injury the loose belt had destroyed the part of the top cover that had the timing index marks. I had to eyeball it, and ended up with the exhaust cam one tooth off, which made it idle rough and the engine vacuum disappear at low rpm, resulting in the loss of power bakes when coming to a stop. I had to take a trip yesterday, so referencing pictures online I counted the number of pulley teeth from where the belt is fully seated to the marks on the cam pulleys. She's good to go now, runs great, it was a miracle it didn't jump timing and destroy the engine. Anyway, does anyone know where I can buy a used or new top cam cover? Not having any luck online. Thanks.

    On a related subject if you did n ot replace the water pump-it would be wise to go back in and replace it. I have seen these engines ruined by a water pump going bad-as in the bearings going bad.

    I thought I had the part you need. The one that covers the top of the cam sprockets with the timing notches-but I cannot find it. I will check back later if I find it.

      Hi Jimo and Spook. I bought one of those Aisin kits, so it has a new water pump, idler, tensioner, tensioner pulley and belt. Yeah, it's the plastic top cover over the timing belt that had the timing marks that I need. Thanks gentlemen.

        I was just going to add to this thread that if Jimo's kind offer doesn't pan out for you (and for the future reference of others), the parts sources I use show the p/n you're looking for should be 9135560 "Inner timing cover -upper" (the upper half of #16 in Volvo parts schematics) which will have the requisite cam sprocket timing marks. On the 4-cyls w/OHC, this kind of part would be called a rear timing cover. It does indeed appear to be long discontinued at Genuine Volvo parts houses, but they may periodically be found elsewhere online. A google search turns up two active references to that part number at the moment -one new on Amazon (seller MySwedishParts) and one used on eBay (seller in Florida). If you're looking in yards, fitment is 1995-1997 960 and 1998 S90 with B6305 engine.

    Dear Mr. Weekend,

    Hope you're well. By "top cam cover" do you refer to: (a) the cover at the front of the engine - which must be removed to gain access to the timing belt (#9458049) - or (b) to the cover at the top of the engine, that goes on top of the ignition coils (Part #1397808).

    The timing belt cover is available, e.g., https://www.eeuroparts.com/Parts/28420/Timing-Cover-Upper-9458049/ .

    The engine top cover (#1397808) cannot be had from a U.S.-based Volvo dealer, but should be available from a salvage yard. I'm pretty sure it was used on most Volvo six-cylinder engines.

    Hope this helps.

    Yours faithfully,

    Spook
