Is the GM 3800 Series 2 a good motor?
depends, there is a 3800, and a 3800 series 2 and a series 3 as well, the series 1 was a good motor,, the series 2 has , or can have problems with the Plastic intake melting from the EGR tube into the coolent passages near the throttle, and flooding the engine without warning full of engine coolent,, the series 3 when to a cast alum intake again,,
Is there a problem with the Buick 3800 V6?
The Buick 3800 V6 is a fairly reliable engine, but coolant leaks on the Series II 3800 engines with the plastic intake manifold have been a problem. The OEM intake manifold gasket tends to deteriorate after 60,000 or so miles in the area that seals the cylinder head coolant passage to the manifold.
What’s the difference between the 3800 and 3800 Series?
Both engines share the same engine blocks, but compression is reduced from 9.4:1 in the L36 to 8.5:1 for the L67. Power is up to 240 hp (180 kW) and 280 ft�lbf (380 N�m) of torque. Final drive ratios are reduced in most applications, for better fuel economy and more use of the engine’s torque in the low range.
What was the stroke of the 3800 engine?
Although the stroke for the 3.8 L engine remained at 3.4 in (86 mm), and the bore remained at 3.8 in (97 mm), the engine architecture was vastly changed. The piston connecting rods were 1 in (25 mm) shorter, so the crankshaft was redesigned.

When did GM stop making the 3800 V6 engine?
GM built and installed more than 25 million of the 3800 model V6 engines in its vehicles between 1975 and 2008.
Is there a recall on the GM 3800?
Another coolant leak problem prompted GM to issue a recall on certain 2000-’03 model year Chevys, Buicks and Pontiacs with the 3800 engine. The coolant leak on these engines was at the gasket between the intake manifold and throttle body or, in some cases, between the upper and lower intake manifold.
Why is the GM 3800 engine so reliable?
One of the reasons why the 3800 has had such a long production run is that it has been a very reliable, trouble-free engine for the most part. Many of these engines have racked up well over 200,000 miles with normal maintenance. One of the few trouble spots has been coolant leaks on the Series II 3800 engines with the plastic intake manifold.
