By far one of the easiest engines to do nearly any work on... I'll even go on a limb and say its more easy then the 425 in the '79..... EVERY spark plug is in direct sight and super easy to get to (not so on the 425... anyone that knows that #7 cylinder knows that I mean) and stuff like changing the water pump is just about as easy, if not more easy.... only downside would be something like swapping out the cam, on the Olds, the enigne would have to be pulled. In all the work I did on this... which is basically any and all engine work short of removing valve covers/manifolds.... the most difficult thing was changing the PCV valve, just from the position of the rubber grommet.... a dream to work on.
The 4.9 is a PITA to work on... it really is... even something as simple as spark plugs, are just a PITA... I swear I hate working on that car because there is no room.... I am not looking forward to putting plugs in it tomorrow, it is all done by feel and I don't even remember where the freakin holes are... it really sucks.
Honda/Toyota are typically tought to do any decent work on just because everything is cramped in...
VW has to be the worst.... replacing a freakin water pump on a '94 Jetta 2.0... it was hell... EVERY engine accessory had to come off, the wheel fender thing, air intake, washer fluid thing, THEN the kicker... the freakin timing belt and pully! my gosh I told myself I'll never own a VW for that reason.... well, that and parts are so freakin expensive....
atleast I know that I wont be getting a vehicle more difficult to work on in the futre... the Jeep and 4.0 I6 are pretty stright forward, decent amount of rooom... and, well, the I6 is a nice design in that stuff like plugs and wires are easy to get to... longitudinal mounted so accessories are easy to get to etc...
